A gunman opened fire in a classroom at a Louisiana trade school today, killing one student and wounding another, police said.

Calvin Joseph Coleman, 22, was arrested about an hour after the shootings, Assistant Police Chief Chris Stanfield said. Police said he had registered at Louisiana Technical College but had not attended classes for several weeks.

The shootings happened about 11:30 a.m. in an electronics class at the vocational-technical school's Natchitoches campus, Stanfield said. Three students and a teacher were in the room, police said.

"He came into the classroom and fired four or five times," Stanfield said.

Investigators said they believe the dead man, identified as Terome Silvie, 32, was the intended target and the wounded man was a bystander. Silvie was shot four times, while the other man was hit by a bullet fragment, police said.

Police Chief Ralph Peters said after the shootings the gunman jumped into a car and left with someone who had been waiting for him. Police would not say whether the other person had been arrested.

The wounded man was treated for a minor leg wound and released from the hospital, police said.

Police were not sure of a motive in the shootings, Stanfield said.

According to the state corrections department, Silvie was paroled in March 2002 after serving slightly less than seven years of a 20-year prison sentence for attempted manslaughter. That charge stemmed from a 1995 robbery in which two men were wounded.
