Deborah Brashers is speaking out as police announced a breakthrough in the so-called Yogurt Shop Murders. The victims were Jennifer Harbison, her sister Sara, and their friends Amy Ayers and Eliza Thomas. The teens were found slain at a yogurt shop in Austin, Texas, in 1991. The slayings are the subject of the new HBO docu-series "The Yogurt Shop Murders." Police say Brashers’ father, Robert Eugene Brashers, is behind the crime, established by new DNA technology.
