A sheriff’s office in New Mexico has named the man suspected of fatally shooting a tribal police officer on the Navajo reservation.

The McKinley County Sheriff's Office identifies the suspect as Kirby Cleveland in a report obtained by the Navajo Times newspaper.  Cleveland is in federal custody, but the FBI is not commenting on the case.

The Sheriff’s Office was among the law-enforcement agencies that responded early Sunday when 27-year-old Navajo Nation Officer Houston James Largo was shot on a county road after stopping a vehicle. Deputies reported that Largo was found lying about 50 yards from the vehicle with his duty pistol by his feet. He had been shot twice.
