The sheriff's office responded to a call Thursday afternoon at a home near Yokohl Valley Drive near Balch Park Road. When investigators arrived on the scene -- they found two bodies in a burning car.
Detectives say an elderly man and woman died of a gunshot wound. They say the car remained on -- after the murder-suicide and caught fire.
Investigators have not released their names -- but say they may have a motive.
Sgt. Chris Douglass said, "Both people had deteriorating health issues so that may have been a factor for the situation."
Autopsies have been scheduled for early next week.
