BATON ROUGE, La. -- A young woman killed two female students in a college classroom at a vocational college Friday, then killed herself, police said.

The students apparently were shot in their seats in the second-floor classroom at Louisiana Technical College, Sgt. Don Kelly said.

Officers ran into the building within four minutes of the first 911 call, which came at 8:36 a.m., he said.

"There was mass pandemonium, people running," Kelly said. "One officer - the first into the classroom - told me he could still smell gunpowder."

The students' names and ages were not immediately released, and it was not clear whether the shooter also was a student.

The school offers classes in a dozen subjects including early childhood education, practical nursing, drafting and welding.
