ODANAH, Wis. - The leader of a Lake Superior Chippewa tribe says a sheriff's deputy has fatally shot a 14-year-old boy on the tribe's reservation in northern Wisconsin.

Bad River Band Chairman Robert Blanchard says 14-year-old Jason Pero was killed Wednesday in Odanah by an Ashland County sheriff's deputy. The Ashland County Sheriff's Office said its dispatchers received a call about a male subject walking down the street armed with a knife about 11:40 a.m. and a responding deputy fired shots, striking the suspect. The boy was pronounced dead at Memorial Medical Center in Ashland.

Sheriff's officials say the deputy involved in the shooting was not injured.

The Wisconsin Department of Justice has been asked to investigate. Blanchard says state agents were at the reservation Thursday.
