A California death row inmate convicted for the 1983 Chino Hills hatchet and knife killings of four people has lost his bid for a third round of DNA testing.
Kevin Cooper claims he was framed and says more sensitive DNA tests on a T-shirt, a speck of blood on a paint chip and a vial of his blood would prove the 53-year-old inmate isn't the killer.
San Diego Judge Kenneth So ruled that Cooper failed to show why more DNA tests are needed. Two previous DNA tests of the items concluded Cooper was the killer, according to the Riverside Press-Enterprise.
Cooper had escaped from a nearby prison two days before the killings of Doug and Peggy Ryen, their 10-year-old daughter Jessica and 11-year-old neighbor Christopher Hughes.
