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.

New DNA testing planned in JonBenet Ramsey’s 20-year-old cold case murder

jonbenetA new round of DNA testing is underway to hopefully solve JonBenet Ramsey’s 20-year-old murder, according to Colorado investigators and the district attorney’s office.
The decision comes after Boulder Daily Camera and 9News analyzed lab results linked to the 6-year-old’s murder that uncovered flaws while testing DNA evidence. The investigation found that forensic evidence did not support previous District Attorney Mary Lacy’s efforts to clear JonBenet’s parents, John and Patsy Ramsey, from suspicion in the case.
