EVIDENCE SEARCHEVIDENCE SEARCH

NOVA SCOTIA GROUND SEARCH AND RESCUE ASSOCIATION

EVIDENCE SEARCH All Searches will be done in conjunction with a police agency.

In Nova Scotia for HRSAR, that will mostly be the Royal Canadian Mounted Police or HRM Police.

EVIDENCE SEARCHMost evidence searches are usually dealing with serious crimes (i.e. murder, sexual assault).

EVIDENCE SEARCHIf you are asked to become involved in an evidence search, some of the things that will be asked of you are:

ConfidentialityDo not discuss with anyone what you findWhat you may seeWhat you may hear

EVIDENCE SEARCHAs with most serious criminal investigations, evidence which is gathered or not gathered should not be common knowledge.You could be summoned as a witness in a court of lawReason for age restriction - over 19 for HRSAR – Christie Salter caseSince it is a not a primary response responsibility of GSAR, members are not “expected” to attend.

EVIDENCE SEARCHWhen asked to become involved in an evidence search, you may or may not be told what you are looking for.i.e. if you are looking for a missing person, this would be very specific therefore you would be told:

If the police investigator in the case is looking for some type of evidence s/he may not want that information released.The investigator may not even know what kind of evidence she is looking for. The area being searched may contain some unknown evidence which only would be found by a thorough search.

DEFINITION OF PHYSICAL EVIDENCEPhysical evidence is any tangible article, small or large, which tend to provide or disprove a point in question.It may be used to:

Reconstruct the crime.Identify the participant/s.Confirm or discredit an alibi.

CONDUCTING SEARCHESPerson in charge:

This would be the lead police investigator s/he would oversee the search.

Search Manager/ ICIn charge of search and how the search will be conducted:

Search IC will determine the size of the search, type of search, & length of search

Generally conducted during optimum searcher available times – weekendsMaybe seasonally optimized – lower foliage / snowMaybe called early due to impending environmental impact.

TEAM LEADERS Takes instruction from the Search Manager in dealing with the search itself.Team leader is in charge of a group of searchers – it can be a large line/ group

TEAM LEADERS

Any evidence or possible evidence located by the searchers will be relayed to the team leader.Team leader will look at evidence to determine if it is relevant or not.If of interest, the item will be officially discovered and tagged by the police.

SEARCHERSPersons who are asked to become involved in some type of search.They should belong to some specific search and rescue organization.Searchers all come from our community and depending on their background, can offer some type of expertise in their field (i.e. electronic person, expert woodsman who is familiar with the area).

SEARCHERS

Searchers are the most important part of the program. Their dedication to the search will result in the outcome of a successful search.Keep them happy….

SEARCH SITEAll persons who come into a search site or is involved in a search will be signed in.No person will be allowed to get involved in an evidence search unless s/he is signed in and that person is approved by the search manager / IC.

SEARCH SITEOnce that person leaves the search site s/he will enter the log book as signing off the search site.

Once the search site has been searched and the specific task has been completed all materials brought to the site will be cleaned up. (i.e. garbage, flagging tape or any other accessories).

WHEN EVIDENCE IS FOUND

WHEN EVIDENCE IS FOUNDDepending on what is found:

The evidence should only be handled by the searchers finding the evidence. The searcher in turn informs the team leader.

Or how old the evidence may be:

the evidence should not be moved from where it is located. Attempt to keep it in its original state as found.

WHEN EVIDENCE IS FOUNDTeam will advises police personnel on site who is in charge of exhibits:

All evidence found will be marked and recorded in notebooks.Flagging tape is a good way of marking the evidence and the area in which it was found.

WHEN EVIDENCE IS FOUNDOnce evidence is found, all persons in search will stop and wait for further instructions on whether to continue with the entire search or stop.The main reason would be to determine whether continuing on with the search may destroy any further possible evidence.

HOW SHOULD THE AREA BE SEARCHED Every search

conducted is different from the last. This would depend on the circumstances and type of search that is required.

HOW SHOULD THE AREA BE SEARCHED

The area closest to the main target site will be examined very closely.

This area may need to be searched inch by inch.This are may need to be sifted thoroughly.

HOW SHOULD THE AREA BE SEARCHEDAs you move away from the target area, you may need to search the area on your hands and knees. (type IV)As you expand your search, searchers may only need a walk through.Make sure all foreign objects are checked out:

i.e. in a wooded area:Unless you know what you are looking for,

anything that is foreign to the forest floor should be considered as possible evidence.

THE SEARCH SITE

Computer Mapping

THE SEARCH SITEThe Search site or area will have to be marked off in grid search patterns.

Depending on the search site, flagging tape will be used to mark the search area.The search site area is to be broken down into smaller sections or grid patterns with the flagging tape.The sections are to be searched for all possible evidence.

THE SEARCH SITEOnce the area has been thoroughly searched, it will be recorded as completed. The search coordinator will be advised what was searched and if anything was found.Each section to be done one at a time until the whole area is completed.

SEARCH TEAMSpeed is not necessary. Your only concern is that the area you search is done right.If it is done right the 1st time you will not be second guessing yourself wondering did I miss anything.
