Police say that a man told them in a 9-1-1 call that he had strangled his wife and her 10-year-old son two days earlier, and that then the man killed himself.
A dispatcher says Fred Kevin Mitchell told where to find the bodies of Betty Mitchell and 10-year-old Tommy Mitchell at a motel.
In the tape recording released Monday Mitchell can be heard calmly telling a dispatcher the names and ages of his wife and stepson after explaining that he strangled them last Wednesday.
He then directed authorities to a remote area where he was found dead of an apparent hanging.
Police say they don't know the motive for the slayings.
Neighbors said Fred Mitchell had lost his job and had substance abuse problems.
