Scene Investigation and Evidence Collection Discussion 1
are the steps and characteristics of a successful criminal investigation?
First is receiving the call/report or detecting a crime in progress. Once a
crime has been reported or observed by an officer the investigation begins.
Suspects are identified as well as victims and witnesses, Statements are
collected and the suspects are secured so they are not a threat to the officers
and other people on scene. Next evidence of the crime is located, identified,
documented, collected, processed and secured. The suspect is then taken
into custody and transported to a jail where they are booked in. The officer
now begins the paperwork side of things with an arrest custody affidavit. Next
comes the officer’s report and documentation in preparation for the court
process. Now it is a waiting game until it either goes to court or the
suspect and DA’s office reach an agreement. Last is the court process and
is evidence collection so important to a crime scene investigation?
Evidence links the suspect to the crime and provides proof that the crime was
committed. If the officer does a poor job collecting evidence or does not
follow the chain of custody the case is no longer a good one and the suspect
can negatively and positively impact evidence collection? Provide examples from
a particular crime scene featured in Criminal Investigation or another source.
Training and experience have a large impact on whether the evidence collection
goes good or bad. A green officer fresh out of the academy may do a better job
of collecting evidence that the retired on duty old timer. On the other hand
the old timer may have some tricks learned in the field that can help the green
officer in collecting the evidence.
