On April 6, 1975 Denise Oliverson decided to go for a bike ride to visit her parents in Grand Junction after having an argument with her husband. When she didn't return that evening he assumed she had decided to stay the night at her parents. She never arrived at her parents house.

The next day her bicycle and sandals were found under a viaduct near a railroad bridge close to the Colorado River, on U.S. Route 50, along the route she would have taken.

It is suspected she is a victim of serial killer Theodore Robert "Ted" Bundy. Bundy said he dumped her body into the Colorado River. Her body would have been placed in the Colorado River five miles west of Grand Junction. It was not buried. (Information retrieved from NamUs.gov)
