BEMIDJI, Minn., March 21 (UPI) -- A student killed his grandparents Monday and then went to a Minnesota high school and shot a guard, a teacher and five students before killing himself.
FBI Special Agent Paul McCabe said a female teacher, a male security officer and four students were killed by the unidentified shooter at Red Lake High School, but later two of the injured students died from their injuries, reported KARE-TV in Minneapolis.
"We believe that one of those students is the shooter," McCabe said. "At this time, we believe he was acting alone."
McCabe said it was too early in the investigation to suggest a motive. The school was evacuated and locked down following the incident. Several other students were also reportedly wounded.
"Apparently, he walked down the hallway shooting and then he entered a classroom, he shot several students and a teacher, then himself," Roman Stately, with the Red Lake Fire Department, who responded to the scene of the shootings, told KARE-TV.
Stately said the boy used his grandfather's police-issued weapon -- his grandfather was a retired police officer -- in the school rampage.
Red Lake High School, is located on an Indian reservation, about 25 miles north of Bemidji, a town of about 25,000 residents, many of them Ojibway Indians.
