RIVERTON, Wyo. (AP) — The FBI says a law enforcement officer who fatally shot a man on the Wind River Indian Reservation fired the gun on purpose.

FBI spokesman Dave Joly says that Tuesday's shooting near Ethete was not accidental.

Fremont County sheriff's officials say they got a call just before 8 p.m. Tuesday that a man armed with a handgun had shot out the window of a vehicle.

A responding deputy stopped a vehicle missing a window. Sheriff's officials say one of the three occupants was uncooperative and the shooting occurred after reservation police arrived to help.

No information about the man shot to death has been released. Coroner Ed McAuslan says no identification was found on the man's body but an autopsy was planned.
