Police say a couple and their son are dead after an apparent double murder-suicide in a Houston suburb.

Authorities on Wednesday night found the bodies of Lewis Cantrell III, his father, Lewis Cantrell II, and stepmother, Gayle Cantrell.

Sgt. John Jordan with the League City Police Department tells the Houston Chronicle that a .38 caliber pistol was found near the younger man's body.

Jordan says two other siblings were in the house when they heard gunfire, prompting them to run to a neighbor's house and call 911.

League City is located between Houston and Galveston.
