Sherry Eyerly, an 18-year-old pizza delivery driver, disappeared on the evening of July 4, 1982 while delivering pizzas to Riverhaven Drive in Salem, Oregon.

The police found her car with the engine idling, pizza boxes scattered on the ground around it, but no trace of her was found. Despite a search effort by police and her loved ones, she remained missing.

One month after her disappearance, a psychic investigator, John Catchings, was contacted by Salem investigators at the request of Sherry's parents. He saw the ghostly figure of a young woman in his bedroom and believed she was the missing girl. After reviewing the case, he traveled to Oregon and was escorted to the scene of her disappearance by Capt. Will Hingston. He had a vision of a white house and identified the prime suspect, Darrell Jay Wilson, who owned a lime green pickup truck.

Despite being the previous suspect, Wilson's past involvement with drugs, his lack of criminal record and inconsistent behavior profile led investigators to consider the possibility of other individuals being involved. Upon reviewing related cases, they discovered a murder with similar circumstances to Sherry's disappearance, that of Katie Redmond, who was murdered one year after Sherry's disappearance.

The culprit was later found to be William Scott Smith, who was convicted of Redmond's and another victim's murder. However, after further investigation, it was discovered that Smith had been questioned by police near the scene of Sherry's abduction just hours after it took place. This information was gathered through recorded statements from Smith's cellmates, who heard him mention being involved in an incident with a "pizza girl".

In 2006, Smith was interviewed again and eventually confessed to Sherry's murder after being offered a transfer to a different prison. He revealed that he and a friend, Roger Noseff, had planned to abduct a delivery driver and hold her for ransom. Sherry, who was filling in for the original driver, was flagged down and taken into their truck. Smith strangled her before disposing of her body in a river. His confession aligned with physical evidence at the scene and provided previously unknown details, such as the type of pizza ordered and a ransom call made by Noseff.

Smith pleaded guilty to Sherry's murder in 2007 and received a life sentence. He later pleaded guilty to the murder of another victim, Terri Monroe, in 2011. Noseff passed away before Smith's confession. Sherry's body has not been located.
