The identity has been released for one of two men found inside a home near Mannford earlier this week.
The Oklahoma State Bureau of Investigation said one of the men found dead on Wednesday in a home along West Basin Road has been identified as Ward Ray Bartlett, 60.
The Pawnee County sheriff said a physical therapist with home health went to the mobile home for a scheduled weekly visit on Thursday, but couldn't get in and called for help. Deputies discovered the bodies around 12:30 p.m. in separate rooms.
Investigators believe the bodies had been inside the house for multiple days.
The identity of the other man hasn't been released, but officials at the scene said the two were brothers-in-law.
The deaths are being treated as suspicious and OSBI is investigating the possibility of murder-suicide.
The medical examiner will determine the cause and manner of death of both men.
