Foul play does not appear to have been a factor in the death of longtime KGO radio host Ray Taliaferro, whose body was discovered Sunday in the Kentucky town where he went missing on Nov. 10, authorities said.

Police in Paducah, Kentucky, issued a news release sharing initial results from an autopsy performed Tuesday, but they noted that the report has not been finalized.

"Preliminary autopsy results confirm Paducah police detectives' initial findings that foul play is not indicated in the death of Ray Taliaferro," the release said. "Exposure to the elements may have been a factor in the California man's death."

Taliaferro, a 79-year-old resident of San Francisco, had not been seen since Nov. 10, when his wife of six months reported him missing to the Massac County Sheriff's Office in nearby southern Illinois.

The pair was visiting a property that his wife, Charlotte Crawford, had inherited in Brookport, Illinois. Police and a family spokesperson both said that Taliaferro and Crawford were preparing to leave the property in a rental car together, when she went to the rear of the house to check on a window.

When she returned, the car and Taliaferro, who may have been suffering from a memory issue, were gone.

His body was found Sunday by two teenagers in a wooded area of Paducah, about a mile from where he was last seen, police said.
