Debra Kent was just 17-years-old when she vanished after attending a high school play with her parents in Bountiful, UT.
Back in November she'd offered to pick up her brother and hurried away to the parking lot.
But she never made it and while her brother waited at the ice rink, her parents were also confused until midnight, when they realized that theirs was the only car in parking lot.
Several people who lived near the school later admitted to hearing two short, terrified screams between 22:30 and 23.00.
Later, a father told police he'd arrived late at the play and saw a light colored Volkswagen Bug racing away from the school.
A small handcuff key was found in the parking lot.
The key matched handcuffs serial killer Ted Bundy used to try to abduct Carol DaRonch earlier that month but nothing else was turned up.
Minimal skeletal remains were later found, but it wasn't enough to positively identify her and even thoughBundy confessed to Debbie's murder before his execution, cops cannot be certain, so the case remains open.
