Glenda Jean Petersen, 40, vanished after an Independence Day gathering at Lake Thunderbird in Oklahoma City in 1997. Known as Blondie and Sunshine, she was a mother of four with long bleached-blonde hair, a scar on her neck, an artificial jaw, and tattoos of the letter G on her left forearm and B on her left hand. She had a recent broken right leg and was wearing a cast.

As the celebration was ending, Glenda gave her purse and boots to her youngest daughter and accepted a ride from a man she had just met. He was described as a white male about 40 years old, around six feet tall, 180 pounds, with brown hair and a mustache. They left in his dark-colored Chevrolet pickup, believed to be a 1990 or 1991 model, last seen on Highway 9. After that, Glenda was never seen or heard from again.

The Norman Police Department is investigating, but few leads have emerged and the case went cold. Does anyone have information about the man, that pickup, or Glenda’s movements that day?
