Bodybuilding champions Craig Titus and Kelly Ryan entered last-minute guilty pleas in Las Vegas in connection with the death of their personal assistant.
Titus pleaded guilty to charges of second-degree murder and first-degree kidnapping in the death of 28-year-old Melissa James. The woman's body was found in a burned car outside Las Vegas in December 2005.
Ryan pleaded guilty late Friday to arson and battery charges.
The married couple had been set for trial beginning Monday. Now their sentencing is set for July 18.
