Weise was smiling and asked at least one victim whether he believed in God before shooting him, according to witnesses quoted by the Associated Press.
Some of Weise's movements in the school are captured on videotape, Tabman said, but the shootings were not recorded. After he left the classroom, he was soon confronted by four police officers and he shot at them. No officer was hurt, but one returned fire. Tabman said he did not know whether Weise was hit. He was soon back in the classroom, where he pointed the gun upward in his mouth, Tabman said.
Inside the classroom, someone announced that Weise had shot himself and the survivors left. "Chase was still alive and told her to get out," Karla Lajeunesse said, describing the event as her daughter related it to her. The boy later died.
In the immediate vicinity, arrayed in something close to a semicircle, were the bodies of several victims, including Lussier and Alicia Spike, 14, the FBI said. Spike had been in the Lajeunesse home for a taco lunch a few hours before, Karla Lajeunesse said.
Even after Weise was dead, there were moments of terror. As Ashley left the classroom, she spotted a man -- a police officer -- dressed like Weise in bulletproof vest and feared it was another killer, her mother said. The girl spun around and ran in the opposite direction, circling the school gymnasium and racing past the dead guard as she escaped out the same door Weise had entered minutes earlier.
Red Lake school officials have closed all campuses for the rest of the week. Grief counselors from the Red Cross and other agencies are providing help to residents, officials said.
Linda Smith was at the Trading Post, a local grocery store, as the shooting unfolded. After seeing police cars and ambulances rush past the store, Smith said she drove toward the school and saw groups of children running for their lives. That is when Smith started panicking, she said, as she thought of her daughter and stepdaughter, students at the high school, and her other daughter, who attends the middle school.
Smith said her cousin, a student at the high school, ran to her and said there was shooting inside. Frantic, she ran toward the building, but the police stopped her.
"All I care about are my kids," she said. "I didn't worry about myself. I just couldn't get to my kids."
Smith said she saw several children trying to pull the security guard to safety. "The kids tried to get the guard up, but he was already gone," she said. "They were covered in blood."
In a midday news conference, the Red Lake Chippewa tribal chairman, Floyd Jourdain Jr., said the mood on the reservation was one of "utter disbelief and shock."
"We have never seen anything like this in the history of our tribe," Jourdain said.
