What physical evidence did you find at the victim’s home? A box of matches, a space heater, beer bottles, Natalie’s wallet, a V-shaped burn pattern, burned outlet, a protected surface on the ground, crazed glass, and a puddle-shaped burn pattern.
Describe the process that you used to take a sample of the puddle-shaped burn pattern on the floor. Why did you also take samples from the portion of the floor that was not burned? First thing i did was I took the chisel to loosen up some of the wood chips in the puddle-shaped area. Then I used I took tweezers to put loose wood chips into an air tight sealed can. Samples needed to be taken from the portion of the floor that was not burned because you need a control to compare to how the wood was before the burned pattern.
What evidence did the space heater provide? What did the evidence indicate? There was a cloth on the heater, the heater was on when the fire was started on high, and there was a faulty electrical cord. tevidence suggests that it could have caused the fire, but it deosnt seemed to be a deliberate event
What information did you gain from the pictures taken at the scene? The v-shaped pattern often occurs in the area where a fire originated, The crazed glass indicated that crazing is the result of rapid cooling of hot glass by the application of water. The protected surface shows there was an object on the floor protecting the area. The puddle-shaped burn occurs in areas of intense burning, with or without the presence of ignitable liquids in the burn wood floor.
To whom did the fingerprints on the match box belong? What characteristics of the fingerprints helped you to determine they were a match? How long does the average IAFIS search take? Why is there a charcoal strip inside the containers that you used to collect the floor pieces?
Why are these pieces saved after the solution has been prepared for the GC?
What elements were present in the gas chromatograph from your puddle sample? How did
