Police say a Southeast Texas husband and wife have been found shot to death in their home in an apparent murder-suicide.
Port Arthur police identified the pair as John and Patricia Knight, both age 76.
Police Chief Mark Blanton says the couple's son discovered the bodies Wednesday afternoon.
Investigators on Thursday did not immediately say which spouse apparently shot the other before committing suicide. Police did not immediately release a possible motive for the killings but say the couple had unspecified health problems. Investigators did not elaborate.
Autopsies have been ordered.
