48 Hours: Four Teenagers Murdered, Two Murder Convictions; 18 Years Later, Case Is Blown Wide Open(CBS) In 1991, "48 Hours Mystery" correspondent Erin Moriarty began reporting on the brutal murder of four Austin, Texas teenagers. The case has come to be known over the years as the "yogurt shop murders." It’s a story that she continues to cover today. She says, "it's the case I can’t forget."
On the night of Dec. 6, 1991, four teenage girls were found murdered in an Austin, Texas I Can't Believe It’s Yogurt! shop. The crime scene was described by the lead detective as "wholesale carnage."
It took years to come up with any answers. But in 1999, there were suspects and arrests and finally, a sense we knew what had happened.
-----
Springsteen's death sentence was commuted to life. Then, 15 years after the girls were killed, a shocking turn of events: in a 5-4 decision, the court said Scott's constitutional rights were violated during his trial and therefore he should get a new one.
Ultimately, both Scott's and Springsteen's convictions were overturned.
