Florida violent crime investigators are now solving cold cases with the help of a more advanced DNA test. The state has recently started using a test that can zero in on just male genetic material.
Four years ago, a woman was raped early one morning in suburban Gainesville. Despite several leads and tips called in to the Alachua County Sheriff’s Office, investigators had given up hope of finding her attacker and closed the case. Then, a few months ago, state labs began offering a new type of DNA analysis called a Y-STR test.
