Question

You have a suspect on the run in a dry, wooded area; they’ve ditched the gun but are hiding from you. how long do you have to find them before vital proof they fired a gun will probably no longer be on their body?

A. a few hours
B. about 24 hours
C. a few days
D. about a week

Answer 1

A Few Hours

Step-by-step explanation:

Residue on the hands can be difficult to find, even with modern forensic techniques. Part of the reason for this is that the residue doesn’t last for long on hands, particularly if the shooter washes, wipes, or rubs their hands. Studies indicate that even within hours of a shooting, it can be very difficult to find gunpowder residue on the hands of a shooter.

Answer 2

C. a few days

Step-by-step explanation:

The evidence that we will have to investigate is the gunshot residue on the body of the suspect. When a person fires a gun there will be a deposition of material from the components of the chemicals present in the gun. This deposit is called gunshot residue and consists of particles of the propellant or explosive primer.

Experimentation has shown that the period of time that is person will test possible for gunshot residue is 5.27 days.
