determine origin and cause ONLY(Michigan V. Tyler 436 U.S. 499, 1978)

Exigency
• Please note that the IC shall have DFD personnel remain on scene until relieved by the Investigators
• If you leave for any length of time, we have to request a search warrant
• By leaving, you have eliminated exigency

What else can you do to help us?
Slow down your overhaul-if you take it out, you’ll have to put it back
• Let us look at the fire first
• Overhaul can be completed after we’re done
• Over-zealous overhaul may slow the victim’s insurance payment, but do enough to prevent re-kindle.
