His body was found at 6:30 a.m. Sunday.

KTVA was told by the Department of Public Safety that an autopsy was done Monday, but for some reason the state medical examiner's office still has not chosen to release the cause of death.

A source close to the case says that Keyes was on suicide watch at one point and then was taken off. A spokesperson for the Department of Corrections said there would be no reaction to that statement because of the ongoing investigation by troopers.
