Question

1. How does trace evidence end up transferring to the crime scene, suspect, or victim? Discuss some of the ways that this might happen.

Answer 1

Answer:
Trace Evidence ends up transferring to either the crime scene, the suspects or the victims by either coming in direct contact with an individual or by second hand contact. This happens through several ways as an individual can directly touch or handle the evidence and cause the transfer. Another way that this might happen is if someone is in contact with another person that has touched the evidence. This would be second hand contact as the person is doing the actual transferring of the evidence. But no matter how the transfer happens, it is the job of the forensic scientist to determine how the transfer of the trace evidence happened.

Answer 2

 evidence can end up transferring to the crime scene through Locard's Exchange Principle, which states that whenever two things come into contact with one another, there is an exchange of physical material A.K.A evidence. This exchange is most often done through physical contact, such as a struggle or a suspect attempting to hide evidence or alter the crime scene. It can even involve a suspect's shirt sleeve brushing against some wet paint.
