An 82-year-old man is accused of killing his son and grandson in their home in a small Collin County town in Texas.
Fairview police found the bodies of Paul Tanner Jr., 59, and Ryan Dawson Tanner, 23, shortly before noon Friday.
Paul Tanner's estranged wife called police after seeing a body slumped over in a chair inside the home in the 1300 block of Red Oak Trail.
The responding officers entered the home and confirmed that the person spotted through the window was deceased. While searching the home, officers discovered another body in a bedroom.
Police said both were shot in the head, most likely early this week.
The Tanners lived in the home with 82-year-old Paul Alexander Tanner Sr., who was later found at an Addison motel and taken into custody.
Police said the grandfather was unconcious when they found him and was treated at an area hospital.
The latest news from around North Texas.
Police said they know of only one domestic call to the home, and that it did not involve the grandfather.
