Investigators believe the 4-year-old son of an East Texas law officer had used her gun to fatally shoot himself.
Tyler police say Jaylen Johnson died Sunday afternoon in the apparent accidental shooting.
Smith County sheriff's Chief Deputy Bobby Garmon told KLTV-TV that the shooting happened in Officer Andrea Johnson's personal vehicle. She works at the Smith County jail but was not on duty at the time of the accident.
Authorities say the boy was dead on arrival at a Tyler hospital.
Further details on the investigation were not immediately available Monday.
