New Delhi, Sept. 27 -- Authorities have identified Robert Eugene Brashers, a deceased serial killer, as the suspect in the brutal killing of four teenage girls in Austin, Texas. Brashers, known for violent crimes across multiple states, died by suicide in 1999 during a police standoff.

In 1991, 17-year-old Eliza Thomas, 13-year-old Amy Ayers, 17-year-old Jennifer Harbison, and 15-year-old Sarah Harbison were found gagged, tied with their own clothing, and shot in the head inside the 'I Can't Believe It's Yogurt!' shop. The crime scene had been set on fire to destroy evidence.
