[narrator] Then, Pam Hofsass
attends a conference for homicide detectives, where she learns
how popular familial DNA sites can be used to solve crimes. Instead of looking for
an exact perfect DNA match, we look for a partial match. In other words,
if there is a relative, like a brother, a son, or father, biologically, they are going
to have very similar genetic information
as a DNA profile, and if they would be
in the database, then we could backtrack
and do research on the backend to see if any of those relatives
were in the area or available, let's say, to commit that crime
