Austin police are closer than ever before in solving the notorious 1991 killings of four local girls, dubbed the "Yogurt Shop Murders." "Austin Police have made a significant breakthrough in the 1991 I Can't Believe It's Yogurt murder case and we have new information. Our team never gave up working this case," the Austin Police Department announced on Friday, September 26. "For almost 34 years they have worked tirelessly and remained committed to solving this case for the families of Jennifer Harbison, Sarah Harbison, Eliza Thomas, and Amy Ayers, all innocent lives taken senselessly and far too soon. We have identified a suspect in these murders through a wide range of DNA testing. The suspect is Robert Eugene Brashers, who committed suicide in 1999. This remains an open and ongoing investigation." Brashers, who died by suicide in 1991, was not previously linked to the murders. Authorities also noted that they've contacted the families of all four girls. The update comes a month after the release of the HBO docuseries The Yogurt Shop Murders, which featured new interviews with family members of the four victims, journalists and investigators who previously worked on the case. Where Scott Peterson Stands With His and Wife Laci's Family After Her Murder Brashers is suspected of committing at least three murders between 1990 and 1998 in South Carolina and Missouri. He died in 1999 by suicide while involved in a police standoff. CBS News reported on Friday, September 26, that the gun Brashers used in his own death is "believed to be consistent with a bullet casing found in a drain inside the yogurt shop." The bodies of Thomas, 17, Ayers, 13, and sisters Jennifer, 17, and Sarah Harbison, 15, were found gagged, tied up and shot in the head on December 6, 1991, at an I Can't Believe It's Yogurt! shop in Austin, Texas. The shop had been set on fire. Both Eliza and Jennifer worked at the shop the night of December 6,. Sarah and Amy reportedly met the pair before they closed up shop that evening.

They were eventually released due to lack of evidence. The charges against Pierce and Welborn were later dropped. Though Scott and Springsteen confessed to police, the pair later recanted their admissions and claimed they were forced into making them. Springsteen was convicted of the murders in 2001, but that ruling was overturned in 2006. Scott was similarly convicted in 2002, but his ruling was overturned in 2007.

The outlet similarly could not locate Scott for comment, though his lawyer Ariel Payan said that Scott was still living in the Austin area the last time they spoke. "Being in prison was very traumatic for [Scott]," Payan told the newspaper. "It's an amazing thing they were able to put the pieces together this late in time."
