Austin police have identified a new suspect in the 1991 yogurt shop murders of four teenage girls. They announced Friday that DNA tests point to Robert Eugene Brashers, who died by suicide in 1999. The case remains open, and police plan to share more details at a news conference on Monday. Amy Ayers, Eliza Thomas, and sisters Jennifer and Sarah Harbison were killed at the "I Can’t Believe It’s Yogurt" store. The murders shocked the city and became one of its most notorious crimes. Two men were previously convicted, but their convictions were overturned on appeal.
