Answer

Forensic investigators use numerous scientific methods when attempting to solve a crime. In terms of DNA fingerprinting, specifically, investigators may make observations and collect evidence (such as DNA samples) at the scene of the crime. Next, investigators hypothesize about how the crime was committed and who may have committed it. To test these hypotheses, investigators will often question suspects and compare DNA fingerprints of those subjects to the fingerprints found at the crime scene.
