Accepted Answer

Processing fragile evidence should be the priority as rain can cause damage and contamination to crucial evidence. Therefore, documenting and preserving the evidence first is crucial to ensure that proper evidence collection protocol is followed. Conducting a scene walk-through and dusting for fingerprints using standard powders can be done after fragile evidence is collected and secured.

Accepted Answer

When processing a scene involving the use of a vehicle as an improvised explosive device, finding as many parts of the explosive device as possible is the most important task. This will aid in identifying the type of explosive used and potentially lead to identifying the perpetrator(s) of the attack. Finding the exact time the bomb went off may be important, but it is not the most critical task. Finding all metal parts of the vehicle may be relevant in some cases, but the priority should be on locating parts of the explosive device. Calling the FBI may be necessary, but it is not the most important task during the initial processing of the scene.

Question 6

You are the lead crime scene investigator processing the scene of a hit-and-run accident. Which of the following pieces of evidence would you be most concerned about collecting?&#10;A) Fingerprints on the victim's steering wheel&#10;B) Mud samples from the tires&#10;C) Tire standards form the victim's vehicle&#10;D) Paint transfer on the victim's vehicle

Accepted Answer

Paint transfer on the victim's vehicle can be crucial in identifying the suspect's vehicle. By analyzing the paint transferred from the suspect's vehicle, investigators can determine the make and model of the suspect's car. This evidence can be used to narrow down the search for potential suspects and identify the perpetrator of the hit-and-run accident.

Question 7

Which of the following can be used to determine the direction and speed of a suspect's vehicle in a hit-and-run accident?&#10;A) SEM analysis of the pieces of rubber from the tire&#10;B) Skid marks&#10;C) Glass debris field&#10;D) Location of vehicle parts

Accepted Answer

Skid marks can be used to determine the direction and speed of the suspect's vehicle. SEM analysis of tire pieces can identify the type of tire, but not its direction or speed. Glass debris field and location of vehicle parts can only provide information about the point of impact and the type of vehicles involved.
