AUSTIN, Texas (AP) — For years, the unsolved killings of four teenage girls in an Austin yogurt shop in 1991 haunted investigators in the Texas capital.

Then Friday, authorities announced DNA evidence identified a new suspect: Robert Eugene Brashers, a long dead serial killer linked to several deaths and rapes across the country.

Austin police say they will provide more details Monday of the breakthrough in the cold case, which was the subject of an HBO documentary series released last month, “The Yogurt Shop Murders.”
