Schools, a hospital and other public buildings on the Crow Reservation in Montana were on lockdown Tuesday as authorities searched for a suspect in a shooting that left three people dead.

The FBI said agents were on the reservation investigating the deaths.

Officials said the killings took place about five miles south of Lodge Grass in a remote area of the southeast Montana reservation.

Tribal representative Donald Spotted Tail said public buildings across the reservation were locked down while the search for the suspect took place.

Spotted Tail said the victims apparently were shot. He said he had no other details.

Big Horn County Commissioner John Pretty on Top said the killings occurred at a home and that a family member was a suspect in the killings.
