It was the nation's worst school shooting since two students at Columbine High School in Littleton, Colo., killed 12 students and a teacher and wounded 23 before killing themselves on April 20, 1999.
The rampage in Red Lake was the second fatal school shooting in Minnesota in 18 months. Two students were killed at Rocori High School in Cold Spring in September 2003. Student John Jason McLaughlin, who was 15 at the time, awaits trial in the case.
Red Lake High School has about 300 students, according to its Web site.
The reservation is about 240 miles north of the Twin Cities. It is home to the Red Lake Chippewa Tribe, one of the poorest in the state. According to the 2000 census, 5,162 people lived on the reservation, and all but 91 were Indians.
