Murder by a fellow classmate at Tenn. school

A student fatally shot a 16-year-old classmate during a dispute Thursday at a Knoxville high school, as other teenagers watched in horror as the victim clutched his chest and fell to the floor.

The shooting happened shortly after 8 a.m. at the Central High School cafeteria, Chief Deputy Bill Roehl said, and the suspected shooter was taken into custody minutes later on a nearby street. The suspect and victim knew each other, Knox County School System Superintendent Bill McIntyre said.

"This wasn't a shooting that was a random act," Roehl said. "It was an individual directing his aggression toward another individual, not the school or the students inside the school."

The cafeteria was a popular place to gather before classes started at 8:30 a.m., students said. When the shooting happened, students in the cafeteria began crying and scrambling to leave, while others tried to get in the room, thinking they had missed a fight, witnesses said.

Authorities haven't released the names of the victim, who died at University of Tennessee Medical Center, or the suspect. No other students were injured.

The school, which has about 1,400 students, was placed on lockdown after the shooting. Classes were dismissed and students were bused to a nearby church so they could be picked up by their parents.
