A suspect in an Oklahoma double homicide is found dead in Texas.

Authorities say 35-year-old Jeffery Scott Baker took his own life with a self-inflicted gunshot wound. He was found deceased in Tuesday in Reeves County, Texas. Baker was a person of interest in deaths of his parents 71-year-old Fred Baker and 70-year-old Barbara Baker. The couple was discovered in their Clayton, Oklahoma, home late last week following a welfare check.

The Oklahoma State Bureau of Investigation says no other suspects are at large and that the investigation into the case remains ongoing.
