BATON ROUGE, La. (AP) -- 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.
Police say all three victims were nursing students, reports CBS affiliate WAFB.
The incident came on the heels of two attacks in public places. In Portsmouth, Ohio, a teacher's estranged husband charged into her classroom Thursday morning, firing a gun, then stabbing her. He later killed himself; the teacher survived.
In the St. Louis suburb of Kirkwood, Mo., a man who had lost a free-speech lawsuit against the government stormed a council meeting and killed three city officials and two police officers, critically wounding the mayor.
