Irony: the real killer was arrested 2 days later and had the murder weapon on him, but it was never matched against the Austin murders. He killed himself in 1999. https://en.wikipedia.org/wiki/Robert_Eugene_Brashers
Fascinating history. 3 years for a 12 year sentence as the result of good behavior, huh. Amusing. I suppose if someone were to attempt to murder you or someone you love, your best shot is to kill them after their release and then behave well. Then you will have likely saved society from a repeat offender and perhaps you’ll serve a few years. A sacrifice well worth it.
I had heard about this case but I didn't realize they had finally identified the perpetrator. What an awful human being he was.
