Executive Summary

Synopsis

As crime analysts for the Massachusetts State Police, we are assigned to the Violent Crime Unit.

On 1/20/10, our supervisor requested that we analyze a series of sexual assaults and a related

murder and produce a project-briefing book report of our findings, analysis and

recommendations. The briefing book shall include any spreadsheets, chart, graphs or maps as

needed to support the analysis and recommendations.

The suspect was described by the victims as a muscular, athletically built, male Caucasian,

between 25 and 35 years of age, weighting between 150 and 225 pounds and from 5 feet 8 inches

to 6 tall. All the victims stated the attacker was very articulate in speech, but very demanding,

demeaning, and specific in his sexual demands. Several stated he had alcohol on his breathe but

was not drunk; on occasions, he had bloodshot eyes and smoked a small cigar. Some of the

victims observed multiple military types of tattoos on the suspect.

Tasking and Methodology

We will break down the incidents and utilize MS Excel formulas to analyze time, space,

behavior, victims, and offenders. In addition, we will prepare a briefing book that includes the

following elements:

Section V: Appendices

Key Findings

It is highly likely that additional rapes and sexual assaults will occur on a Saturday night or

Sunday early morning between the hours of 10 pm and 2 am. There is a strong correlation

between the assaults and major holidays. In addition, since a number of the assaults took place

over Mother’s Day weekends, there may be an underlying psychological issue between the

offender and his mother.

Each of the assaults occurred within a few miles of an interstate highway, cemetery and local

colleges. It is likely that the offender will continue to select his victims in locations that are near

to the Massachusetts Turnpike (I-90), close to college campuses, and likely with cemeteries

nearby. It is likely that the offender prefers areas of the city that are close to local bars and all-

night restaurants in addition to proximity to college campuses and cemeteries. The offender will

likely continue to choose his victims from similar activity spaces.

It is unlikely that the opportunistic behavior of the offender will change. It appears the

motivation of the offender is to cleanse the women of whatever he perceives is evil or dirty. It is

unlikely that the death of the most recent victim will stop the offender. It is likely the offender is

taking items from the victims as trophies of his success. His need to belittle the women he

assaults may be a reflection of how he has felt belittled by an important female in his life. The

escalation in violence may indicate he is not feeling fulfilled unless the victim is fully degradedand demoralized.

Caucasian women in their early 20’s are being targeted by this offender. At particular risk are

those who live near college campuses and are students. It is likely the offender targets his victims

after seeing them either at the same bar he is going to or at a place he would stop for food after

being at a bar.

Forecasts

It is likely the next assault will occur on 15 January 2012, which coincides with Martin Luther

King weekend and is a Sunday, or on 8 April 2012, Easter Sunday.

The offender will likely return to either Worcester or Chicopee for his next attack. He is unlikely

to murder his next victim, having learned what not to do with victim 10. However, the overall

violence of the assault is not likely to diminish much.

Recommendations

Focus of the investigation should likely be near bars, all night restaurants, and college campuses,

within 4 to 6 miles off the Massachusetts Turnpike in the cities of Chicopee, Boston, and

Worcester, MA.

Probable provocation factors might drive the suspect to include an aggressive female who fights

back and is not submissive to him.

Probable interrogation techniques would include employing the expertise of an aggressive

female interrogator, and the offender should be confronted directly.

The sexual assault offender in this case appeared to change his style of offense as the serial

sexual assaults progressed. Initially, the offender seemed to be a disorganized offender,

appearing nervous and in a hurry for the first known victim. After developing and honing thesexual assault technique the offender became increasingly organized. The fact that body of the

last known victim was not hidden or moved as would be the case with most organized offenders;

it is likely because the offender did not intend to murder the victim. However, since the serial

sexual assaults intensified and culminated in the death of the last victim, it is likely that the

offender will become more organized in the murder of subsequent victims.

Section II: Crime Series Matrix Analysis

Time Matrix

Analytical Findings

Cyclical Distribution: How crimes repeat themselves (hour of day, day of week, day of month)

Facts: All of the assaults took place on

Saturday or Sunday. The majority of the

assaults took place between 10 pm and

2 am. There is no pattern to the days of

the month of the assaults.

Findings: It is highly likely that

additional rapes and sexual assaults will

occur on a Saturday night or Sunday

early morning between the hours of 10

pm and 2 am, because the majority of

the previous assaults were within this

time-frame. The only assault that did

not fall into this time-frame was

against victim #10, where the coroner

determined that the time of death was

between 6 pm and midnight on a

Sunday night.

Linear Distribution: How case

distribution pattern and timeline relate to

one another (cluster, uniform, random)

Facts: The frequency of the assaults

decrease over time. He has not

assaulted anyone in the 3rd

quarter of

2007, 2008 or 2009. The amount of

time between assaults is not consistent.

Figure 1: Number of days between attacks and day of the week



5

Findings: The initial assaults occurred within 1 to 2 months of each other. Once the assaults

included rape, the interval between crimes increased from anywhere between 3 and 6 months.The final interval, of 595 days, is likely an exception. Potential reasons for the break include

imprisonment, a rape incident that was not reported, or a rape/murder where the body has not

been discovered. The most likely reason is that he was incarcerated without his DNA being

taken, which would explain why it isn’t in CODIS.

It is likely the next assault will occur anywhere between Tuesday, 4 January 2011 and

Sunday, 12 August 2012. Using ATAC, the next assault is predicted to occur on 8 April 2012,

Easter Sunday. The average prediction date is 15 January 2012, which coincides with Martin

Luther King weekend and is a Sunday.

Temporal Environment: Correlates the temporal problem with other temporal factors (day or

night, holiday, special event)

Facts: The majority of the assaults

took place on the weekend of a

national holiday or event. The first

February assault was the only one

not on a holiday.

Findings: There is a strong

correlation between the assaultsand major holidays. The majority

of the holidays coincide with either long-weekends or breaks for most colleges. There is likely

some connection between the breaks and the opportunity for assault. In addition, since a

number of the assaults took place over Mother’s Day weekends, there may be an underlying

psychological issue between the offender and his mother.



6

Activity Schedule: Can tell activity space of the perpetrator and victim (sleep/work schedule,

days available)

Facts: Commits crimes on Saturday nights. The average time of assaults, eliminating the

outlier victim 10, is 1:14 a.m. The offender reportedly smells of alcohol. The early victims

were either at a bar earlier in the evening or near a fast-food style restaurant. The later victimseither worked at or were at bars earlier in the evening.

Findings: The offender likely has a traditional job, where he works Monday through Friday

since all of the assaults take place on Saturday night. The assaults generally occur around 1

am on Sunday morning, demonstrating that the offender may be out drinking in a bar before

the assault. He may have seen his victims at the bar prior to the assault. For those victims who

were not at a bar, they were potentially identified as targets by the offender because he was

frequenting the location after drinking at a bar.



7

Space Matrix

Analytical Findings

Spatial Distribution: How locations of crime relate to one another

Facts: The Massachusetts State Police-Violent Crime Unit supplied data for a series of sexual

assaults and an associated murder statewide. The sexual assaults and murder occurred in

clusters and were uniform in their spatial distribution. The offender’s first three known sexual

assaults occurred in Boston, Suffolk County, Massachusetts. These initial sexual assaults

occurred within one mile of one another, and these offenses took place in the offender’s

vehicle. The initial victim’s encounter sites were within blocks of their workplace and/or

homes. However, the third victim’s assault location was approximately four miles from the

encounter site.

Figure 2: Boston, MA assault locations

Assault & encounter site Encounter Site only Assault site only



8

The offender traveled west approximately 35 miles to Worcester, Worcester County,

Massachusetts where the fourth, sixth, and eight victims’ assaults occurred. The Worcester

sexual assaults were clustered in a one to three mile radius of each other. The fourth victim’s

encounter site was within a few blocks of the victim’s parked car. However, the crime scene

for this victim was approximately 17 miles from the encounter site. The remaining of the

Worcester sexual assaults occurred inside the victim’s residences.

Figure 3: Worcester, MA assault locations

Following the sexual assault of the fourth victim, the offender again headed west

approximately 42 miles to Chicopee, Hampden County, Massachusetts, where his fifth,

seventh, and ninth sexual assaults occurred. The encounter site for the fifth victim was in the parking lot near her residence. The crime scenes for these victims were in their residences,

and again all encounter sites occurred within one to three miles of each other.




9

Figure 4: Chicopee, MA assault locations

The offender drove east approximately 75 miles to Boston, Suffolk County, Massachusetts for

his last known sexual assault/murder. The sexual assault took place within one to three miles

of the first three encounter sites, and took place in the victim’s home.

Findings: The greatest distance between encounter sites was approximately 75 miles from

Chicopee, MA to Boston, MA. The clusters of sexual assaults occurred in three distinct city

locations, Boston, MA, Worcester, MA, and Chicopee, MA. The cities are arranged in a linear fashion from the easternmost city of Boston approximately 35 miles in a western direction to

Worcester, MA, and continuing 42 miles further westward in a linear fashion to Chicopee,

MA. Within each city cluster, the sexual assault encounter sites occurred in one to three miles

of one another. It is highly likely that future sexual assaults perpetrated by the offender will

occur within these city boundaries.

Spatial Environment: Describes the correlation between significant locations and other spatial

phenomena

Facts: The offender encountered his initial victims in downtown urban areas. The first four victims were encountered while walking near a Metro station, bus stop, or bar and fast food

restaurant. All but the last two victims of sexual assaults that occurred in their residences pre-

assault activities were either serving or spending the evening at local bars or restaurants.

Many of the victims were students at local college campuses that were within short distances

from the encounter sites. Two of the crime scenes were in area cemeteries.




10

Findings: The offender’s sexual assaults in Boston, MA were three to six miles off Exit 20

of the Massachusetts Turnpike. Each of the Boston sexual assaults occurred within one to

three miles of Boston College and Newton Cemetery. Newton Cemetery, the crime scene for

one of the Boston sexual assaults is also within four miles of I90. The offenses that took

place in Worcester, MA were easily accessible from Exits 10 and 11. Two of the three sexual

assaults in Worcester occurred within 4 miles of I90. The furthest distance off Exit11 was to

Bowdoin Street in Worcester, MA, which was a distance of approximately 20 miles. Each of

the Worcester offenses was located within three miles of several local colleges including

Becker College, Clark College, and the College of the Holy Cross. In addition, the assaults

occurred within a few miles of several area cemeteries. Chicopee sexual assaults all occurred

three miles from Exits 5 and 6 off I-90, are within two miles of Elms College, and within two

miles of both Calvary and Fairfield Cemeteries. It is likely that the offender will continue to

select his victims in locations that are near to the Massachusetts Turnpike (I90), close to

college campuses, and likely with cemeteries nearby.

Movement: Describes the dynamics of the spatial problem

Facts: The movement of the crimes is systematic in its spatial relationship. The first three

known offenses occurred in Boston, the movement of the offender headed west to Worcester,

then further west to Chicopee. The offender oscillated between Worcester and Chicopee for

the fourth through ninth sexual assaults in an alternating pattern, before finally returning to his

original sexual assault location in Boston, MA. The spatial movement is very limited within

the clusters of sexual assaults ranging from only one to three miles between the assaults sites.

Findings: It is likely that the offender will continue to commit the sexual assaults in the

Boston area as well as along the I90 Massachusetts corridor. The offender is likely to travel

the Massachusetts Turnpike to both Worcester and Chicopee. As no sexual assaults from the

same offender have been reported beyond the Chicopee city limits to the west and the Boston

city limits to the east, it is unlikely that offender will change his spatial movement. The

offender is also likely to continue to assault victims in close proximity to the Turnpike.



11

Activity Space: Derived by distance or density calculation of known crime scenes

Facts: The activity space surrounding the victim encounter scenes is in highly populated

urban areas with access in both Worcester and Boston to mass transit. The hubbub of activity

is in local bar s and all-night restaurants close to college campuses. Most of the crime scenes

are in residential areas of the cities, but close to business areas and exceptionally close tointerstate highway systems. Two exceptions for the crimes scenes occurred in area cemeteries.

Findings: It is highly likely that the offender’s travel route is the Massachusetts Turnpike. It

is likely that the offender prefers areas of the city that are close to local bars and all-night

restaurants in addition to proximity to college campuses and cemeteries. The offender will

likely continue to choose his victims from similar activity spaces.



12

Behavior Matrix

Analytical Findings

Category: What makes the crime behaviorally distinctive

Facts:

Distinctive crime behavior

The offender is an opportunistic rapist. The offender demonstrated little planning or

preparation. The only planning apparent was in later assaults when he brought cotton cord

with him. There was no concern for the welfare or comfort of the victims. The sexual assaults

occurred during the service of dominance and power. As the assaults escalated the injuries

suffered by the victims were greater than minor cuts and scratches, and excessive force was

necessary to attain victim compliance. The offender burned and sodomized many of the

victims. The offender humiliated the victims through derogatory and demeaning remarks. The

offender also robbed his victims of personal property. In his final known sexual assault theoffender committed a murder.

Modus Operandi (MO) factors

The offender began his serial sexual assaults as a disorganized offender. However, with the

success of each offense the offender learned to improve his skill as a rapist, and became more

organized in his offenses. The offender had low contact with his victims. The offender

brandished a gun in the commission of the crimes. The first victims were forced into a light

van and forced to perform oral copulation on the offender. A condom was used for the rapes

only. Residences where the sexual assaults occurred were entered through unlocked windows

or by forcing the victim into the home through the front door. The offender tied some of hisvictims with cotton cord.



13

Findings: It is unlikely that the opportunistic behavior of the offender will change. The

offender’s motivation is vindictive in nature, and has increased in its intensity and severity

with each subsequent sexual assault. It is likely that that if apprehension of the offender does

not occur, the violent nature of the sexual assaults will continue to escalate. It is likely that the

MO of the offender will remain consistent. It appears the motivation of the offender is tocleanse the women of whatever he perceives is evil or dirty. It is unlikely that the death of the

most recent victim will stop the offender. It is likely that the death of the victim was not

intended.

Signature: Style in which MO is performed

Facts: The signature of the offender is very demeaning and degrading to the victim. The

offender subjected his later victims to torture and humiliation. The offender often took some

things from his victims that were of little value, i.e. their panties, a few dollars, and student

identification. The offender blindfolded some of them with a pillow case. Many of the victimswere burned with a small cigar. The offender quoted a bible verse about cleanliness, and

forced the victims to wash following the sexual assault. In addition, the offender would often

wash the victims himself, soak the bed linens, and in two cases poured kitchen cleaning fluid

over the victims’ bodies.

Findings: It is likely the offender is taking items from the victims as trophies of his success.

As his crimes have progressed, his obsession with cleanliness has also increased. This

obsession after the assaults will probably manifest itself in other areas of his life. For example,

he may be somewhat obsessive about washing hands and his home is likely orderly. His need

to belittle the women he assaults may be a reflection of how he has felt belittled by animportant female in his life.

Evolution: how does the signature and/or MO change over time

Facts: The offender began by forcing victims into a van, brandishing a gun. The early assaults

only included forcing the women to orally copulate. He progressed to abducting the women,

driving to secluded cemeteries and raping the victims. The offender then found a victim,

victim 5, who was entering her home and forced her inside. The assaults escalated from this

point. In some cases he would blindfold the victim with a pillowcase. In all cases he restrained

the victim on the bed. He used the victim’s nylons and belt in the first home rape. From thatincident on, he brought cotton cord with him to restrain each victim. The assaults became

more violent with each progression. He hit and degraded victim 6, in addition he burned

victims 7 and 8 with a cigar. Victim 9 had cleaning fluid poured over her, in addition to

physical abuse, degrading comments and burns. Finally, victim 10 had signs of all of the

previous types of abuse, plus bite marks. Victim 10 did not survive the assault.



14

Findings: It is likely that the offender is finding it more difficult to feel clean himself after

each incident. The escalation in violence may indicate he is not feeling fulfilled unless the

victim is fully degraded and demoralized. It is unlikely the offender wanted his last victim todie. If he views that assault as unsuccessful, he may be feeling inadequate or unfulfilled. If his

tendency to learn after committing each crime continues, he may regress somewhat in his MO

so as not to murder his next victim.

Mission Creep: Describes how the category of crime changes over time

Facts: The offender began with a sexual need and found a victim how he could threaten with

a gun into performing. He brandished a gun for the majority of the assaults. The assaults

moved from oral copulation to include rape then physical assault then sodomy and finally

murder.

Findings: The offender likely seeks both a sexual release and a method of debasing women

that is becoming more difficult to obtain with each passing incident. The escalation in

violence of each assault will likely continue. There is a chance, however, that he will not

murder again, as this may have been an accident.



15

Target Matrix

Analytical Findings

Description: Physical and non-physical appearance

Facts: The average age of all of the victims is 21, with all of them between 20 and 23 years of

age. All victims live near college campuses, with the majority of them being students. All

victims are Caucasian women.

Findings: Caucasian women in their early 20’s are being targeted by this offender. At

particular risk are those who live near college campuses and are students.

Actions: Victim cooperation or non-cooperation

Facts: One victim, number 6, tried to fight off the offender; he retaliated by pulling out his

gun and slapping her. Perhaps because of the presence of a gun, all of the other victims

cooperated with the offender.

Findings: Cooperating with the offender does not spare the victim from physical assault, rape,

sodomy or oral copulation. The offender most likely uses the threat of force and/or death to



16

maintain control over the victims. For the majority of the victims, if they follow his

instructions, he does not murder them.

Motivation: Actions describing why they have been targeted

Facts: The majority of the victims had either been at a bar or restaurant/fast-food store prior to being assaulted.

Findings: It is likely the offender targets his victims after seeing them either at the same bar

he is going to or at a place he would stop for food after being at a bar.

Movement: How the target changes in space, time and behavior

Facts: Began with targeting young women on city streets. Moved to a woman as she was

unlocking her front door. Then progressed to breaking into homes in order to assault victims.

Findings: Victims were initially chosen as they were walking either home or to

transportation. As the offender progressed, he began breaking into homes through unlocked

windows. In one instance he forced a victim into her home by brandishing a gun. It is

unknown how he gained entry into the last victim’s home.



17

Offender Matrix

Analytical Findings

Description: Physical description, weapons, vehicles, property, etc.

Facts:

Offender: The offender was described as a male Caucasian between the ages of 25 and 35,

weighing 150 to 225 pounds, and is 5 feet 8 inches to 6 feet tall. The attacker was athletically

built and muscular with multiple military-type tattoos. Victims reported the offender having

alcohol on his breath, but not being intoxicated. The eyes of the offender reportedly were

bloodshot, and he smoked a small cigar. The offender’s speech was very articulate, but was

demanding and demeaning. The offender has been positively linked to all ten reported sexual

assaults and one murder via DNA samples that were collected from each of the crime scenes

or from the victims’ bodies.

Weapon: The weapon that was brandished was a gun. However, the description of the weapon

was not consistent in victim statements, ranging from a small handgun to a large gun, and a

more precise description of chrome gun, in one instance. The offender also used cotton cord

from his pocket to restrain some of the victims.

Vehicle: The victims that saw the offender vehicle gave very similar descriptions. The vehicle

was a light colored or white van with a cargo space in the rear. Inside the van, victims noticed

a toolbox, gym bag, sleeping bag, mattress and pillows. One victim noted that the rear light

did not work when the door opened.

Findings: It is likely that the light colored van is the offender’s primary means of

transportation, and will continue to be used in the commission of the crimes. There is little

that the offender can do to change his physical appearance, so it is likely that will remain

consistent. The offender prefers to intimidate with a handgun, although in victims’ statements



18

the gun was not used to cause harm. With the progression of the sexual assaults the offender

heightened the level of aggression.

Actions: Tells what the offender does during his crime and possibly at other times

Facts: The offender was very forceful during the sexual assaults. In the first few sexualassaults the offender forced the victim into his van under threat of physical violence. The

offender approach initially was from behind the victim, but became more brass in subsequent

assaults when he confronted the victim from the front, and ultimately entered victims’

residences without their knowledge assaulting them in their bedrooms. The offender called

many of the victims by derogatory names, forced oral copulation, rape, and sodomy. The

offender blindfolded, gagged, restrained, and physically assaulted the victims by burning them

with a small cigar. The offender always wore a condom for the rape, but not for oral

copulation or sodomy. As the sexual assaults escalated the offender washed the victims and

soaked the bedding. In the last two assaults, kitchen-cleaning fluid was used to cleanse the

victims’ bodies. In a few instances the offender quoted a verse from the bible aboutcleanliness. In the sexual assaults where the victim survived, the offender took belongings

from the victim including money, jewelry, panties, and a photograph.

Findings: It is likely that the offender feels that women are dirty, thus using a derogatory

word like “whore” while assaulting the victims. The aggression of the sexual acts escalated

with each assault, and the offender’s treatment of the victim became more demeaning and

abhorrent. The offender apologized on one occasion to a victim after he hit her implying that

the “devil” caused him to strike her. That was the only reported incidence that indicated any

feeling of remorse toward the victim, however meaningless. The offender more often treated

the victims as less than human, with complete disregard and disrespect. The act of cleaning

the victims is likely to be the offender’s need to clean the ugliness of womankind, not

preventing apprehension.



19

Motivation: Underlying reason for being a criminal

Facts: The motivation for these sexual assaults appears to be a self-fulfilling need. Power and

control and anger seem to be the offender’s motivating factors. Yet, sexual gratification is a

secondary effect. The offender is a vindictive rapist, where women are the central and

exclusive focus. The offender’s behavior is physically injurious and appears to intentionallyand primarily humiliate and demean the victims.

Findings: It is likely that the offender is vindictive in nature. The offenses were characterized

by humiliating, degrading and physically harmful behavior toward the victims. It is likely that

the motivating factors are complex, and have deeper subconsciously motivated causation.

Movement: Describes how offender changes behavior, spatial environment, timing, and target

selection as progresses in criminal career

Facts: The offender’s spatial environment changed from the sexual assault in the van to theresidences of the victims. The offender occasionally committed the crime at a location

separate from the victim encounter site, however as the rage and sexual assaults escalated the

offender preferred to assault the victims in their residences. The timing of the crime and the

selection of the targets remained relatively consistent throughout the serial assaults. The most

obvious movement was exhibited in the behavior of the offender. The offender’s behavior

became more aggressive and violent with each successive assault, culminating in the murder

of the last sexual assault victim.

Findings: It is likely that the movement of the offender will continue to escalate in violence

until apprehended or dead. The movement of the spatial environment will likely stabilize. Theoffender has successfully avoided apprehension, and has perfected his stalking and victim

selection to likely feel invincible. It is likely that the timing of the offenses will change as the

ability to resist the desire for sexual assaults declines. Waiting for the next meaningful date

will likely be out of the realm of the offender’s ability to restrain the impulse to commit these

more violent assaults.



20

Section III: Forecasts

Time, Behavior, Location for Next Attack

It is likely the next assault will occur on 15 January 2012, which coincides with Martin Luther

King weekend and is a Sunday, or on 8 April 2012, Easter Sunday.

The offender will likely return

to either Worcester or

Chicopee for his next attack.

He is unlikely to murder his

next victim, having learned

what not to do with victim 10.

However, the overall violence

of the assault is not likely to

diminish much.

Target and Offender Profile

Target Profile

Caucasian women, ages 20 to 23, who live near college campuses and within a few miles of

Interstate 90, plus frequent bars or work at all-night food establishments, are particularly at risk.

Offender Profile

Based on the modus operandi and signature of the offender in addition to the spatial and

temporal elements of the crime, a profile of the offender has been developed.

Demographics

The physical attributes of the offender described by the victims are a Caucasian male between

the ages of 25 and 35 standing between 5 feet 8 inches to6 feet tall, and weighing 150 to 225

pounds. It is highly likely that the offender lives near and has knowledge of the cities where the

offenses occurred. The likelihood of his original primary residence being Boston is high since

the first three attacks occurred in the Boston area. It is likely that he is married.

Personal and physical characteristics

The victims stated that he was articulate, yet demanding and demeaning. Thereby, it is likely that

the offender is of above average intelligence. It is likely that the offender works in an occupationwhere some travel along the Massachusetts Turnpike is required. It is likely that at one time the

offender was in the military. The offender does not likely work on the weekends. The offender

knows where the cemeteries are in the cities of the sexual assault and may work in the cemetery

field. The psychosexual development of the offender is immature. The van is light colored and

probably in fair condition. The spatial attributes of the van yield more into the development of

the offender profile. The fact that the victims observed a mattress, sleeping bag, toolbox and gym

bag likely indicate that the offender used the van as more than just a method of transportation. It



21

is likely that the offender used the van for work or for rest or sleep during travel. It is likely that

he observed or stalked his later victims using the van while assessing the opportunity for the

assault.

Habits

The offender is a smoker, preferring small cigars. Described as muscular and athletically built,the offender likely worked out. It is probable that he frequented bars.

Pre-offense behavior

It is likely that prior to committing the assaults the offender went to bars. Although, not

appearing intoxicated, the offender’s eyes were described as bloodshot, likely indicative of

drinking or lack of sleep. The motivating factor to the offender’s assaults is anger, power, and

control with sexual gratification as a secondary factor. It is probable that negative events

involving women in his life occur prior to the assaults and abductions. It is likely that the

offender had low contact with the victim, but may have observed them in the bar or restaurant.

Some minimal stalking of the victims is likely, more so with successive assaults.

Post-offense Behavior

The offender washes the victims or forces them to shower themselves, and in the final two

known assaults the victim was washed with kitchen cleaner fluid. He would also occasionally

shower. The offender would rummage through drawers or pants pockets to take tokens from the

victims. The victims’ statements suggested that the offender drove away in a vehicle.

Recommendations to Assist Task Force

Focus of the investigation should likely be near bars, all night restaurants, and college campuses,

within 4 to 6 miles off the Massachusetts Turnpike in the cities of Chicopee, Boston, andWorcester, MA.

Probable provocation factors might drive the suspect to include an aggressive female who fights

back and is not submissive to him.

Probable interrogation techniques would include employing the expertise of an aggressive

female interrogator, and the offender should be confronted directly.

The sexual assault offender in this case appeared to change his style of offense as the serial

sexual assaults progressed. Initially, the offender seemed to be a disorganized offender,appearing nervous and in a hurry for the first known victim. After developing and honing the

sexual assault technique the offender became increasingly organized. The fact that body of the

last known victim was not hidden or moved as would be the case with most organized offenders;

it is likely because the offender did not intend to murder the victim. However, since the serial

sexual assaults intensified and culminated in the death of the last victim, it is likely that the

offender will become more organized in the murder of subsequent victims.

Sexual Assaults/Murder

Information:

Please be on alert. Mass. State Police areinvestigating a series of rapes that occurred9/2/2006 to 12/26/2010 in Boston,Worcester, and Chicopee. The rapes mainlyoccurred in victim’s homes, which were

located near college campuses, cemeteriesand Interstate 90. The suspect is an unknownwhite male, approximately 5’8”-6’ tall, 150-225 lbs., with multiple military-style tattoos.The suspect entered the homes through

unlocked windows and assaulted the femaleresident. The offender drove away from the

scene after the assaults. The final assaultended with the murder of the victim. It is
