Pushing for familial DNA testing in NY

Familial HelixFor 25 years, police in southern Los Angeles struggled to identify the perpetrator responsible for killing at least 10 black women over the course of three decades, known as “The Grim Sleeper.”
DNA samples left at the crime scenes matched nobody in any databases and detectives seemed to be out of leads.
Enter familial DNA testing, a method in which investigators take a sample and look for a match in the databases to determine if it matches that of anyone’s close male relative — the search tests the Y chromosome, passed down by the father — registered in any criminal databases.
