ODANAH, Wis. - The Latest on the fatal shooting of a 14-year-old boy by a sheriff's deputy on a northern Wisconsin reservation (all times local):

2:10 p.m.

The mother of an 8th grade boy fatally shot by a sheriff's deputy on a northern Wisconsin reservation says she believes her son was murdered. Holly Gauthier tells Duluth station WDIO-TV there is no reason to justify shooting a 14-year-old boy. Gauthier says her son Jason Pero was home sick from school on Wednesday and was staying with his grandparents.

Jason's grandfather, Alan Pero, says his grandson "never had one mean bone in his body."

The Ashland County Sheriff's Office says a deputy responded to a report of a male armed with a knife and shot the person after encountering him in Odanah Wednesday. State investigators say a knife was found at the scene. Pero's family questions whether the boy had a knife.

The Wisconsin Department of Justice is investigating.

State investigators say a knife was found at the scene where a sheriff's deputy fatally shot a 14-year-old boy on a northern Wisconsin reservation.

The Wisconsin Department of Justice said Thursday an Ashland County sheriff's deputy responded to a 911 call reporting a male subject carrying a knife while walking Wednesday in the Lake Superior Chippewa reservation in Odanah. Sheriff's officials say the responding deputy fired gunshots, striking and killing the male.

Bad River Band Chairman Robert Blanchard identified the teen killed as Jason Pero. Blanchard questioned why the deputy used deadly force.

The DOJ says its Division of Criminal Investigation is collecting evidence and will turn over its reports to the Ashland County District Attorney's Office, hopefully within 30 days.

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.
