A BIA police officer involved in a shooting in Pryor on Sunday remains on administrative leave.
The officer's name hasn't been officially released, said a spokeswoman for District V of the BIA Office of Justice Services.
Family members of Richard Martinez, the man shot in the incident Sunday night, identified the officer as Allen Plain Bull.
The incident happened at around 10 p.m. Witnesses say Martinez walked 80 yards from his duplex apartment in Pryor to the post office parking lot, where Plain Bull was sitting in a BIA vehicle.
The two men argued, witnesses said, and Martinez allegedly punched Plain Bull. Witnesses said the police officer used a stun gun to subdue Martinez, but when Martinez tried to get back up, Plain Bull is said to have shot him in the back at close range.
Martinez was taken to St. Vincent Healthcare. On Wednesday afternoon, he was listed in good condition at the hospital.
Because a BIA officer was involved in the shooting, the spokeswoman said, the FBI is investigating the incident.
The Office of Justice Service's Professional Standards Division is conducting its own investigation, she said, to make sure the officer followed all the appropriate policies and procedures. That is done in all officer-involved shooting cases, she said.
