Medical officials say some of the victims of the Red Lake High School shooting were shot at close range. The shooting rampage took place late Monday afternoon on the Red Lake Reservation located about 240 miles north of the Twin Cities.
At least three victims were shot in the head. One of those died. Two were flown to a larger hospital in Fargo, North Dakota, where they're in critical condition.
Three victims remain at North Country Regional Hospital in nearby Bemidji in non-critical condition.
Emergency services nursing director Tim Hall of North Country says he thinks there was "an intent to kill."
Witnesses said the gunman -- who was a student -- smiled and waved as he shot five students, a teacher and an unarmed guard. The teen's grandfather and his grandfather's wife also were found dead, and the boy killed himself.
It was the nation's worst school shooting since the rampage at Columbine High School in Littleton, Colorado, in April 1999.
