Marilyn Manson

Armed with two revolvers, Coon opened fire at the alternative school, wounding two students and two teachers. He had a history of mental problems and was known for cursing at teachers and bickering with students.

Police found a duffel bag stocked with ammunition and three knives in a bathroom, but no suicide note, Police Chief Michael McGrath said.

Coon, who was suspended Monday for fighting with a classmate and was under suspension at the time of the shootings, had warned classmates of an attack, but none took him seriously.

Coon, who was white, stood out in the predominantly black school for dressing in a goth style, wearing a black trench coat, black boots, a dog collar and chains, she said.

Henderson, who is black, she said she didn't believe race played a role in the shootings.

"He's crazy. He threatened to blow up our school. He threatened to stab everybody," said Doneisha LeVert, 14. "We didn't think nothing of it."

Police believe Coon, wearing a Marilyn Manson shirt, black jeans and black nail polish, targeted the two teachers he shot Wednesday.

Coon's troubles seemed to come to a breaking point this week. Students said Monday's fight was over God — Coon told his classmates he didn't believe in God and instead worshipped rocker Marilyn Manson.
