A gunman walked into a business school in downtown St Louis and shot an administrator in the chest before shooting himself, police have said.
Police Chief Sam Dotson said the shooting happened at about 2pm on Tuesday. The administrator was a man in his 40s who was shot in his office.
Mr Dotson said both the administrator and the gunman are in surgery. He was unable to say if their wounds were life-threatening. No-one else was injured in the incident.
The shooting happened at the Stevens Institute of Business and Arts, which has about 250 students in programmes including business administration and interior design.
Mr Dotson said officers found students hiding under desks and in closets.
A police dispatcher said the shooting happened on Tuesday afternoon at Hazard Community & Technical college in Hazard.
The dispatcher said the injured teenager was being taken to the University of Kentucky hospital.
Conor Duff, the college's evening co-ordinator, said the shootings happened at about 4.30pm (9.30pm GMT) at the campus, 90 miles south east of Lexington.
Mr Duff said police searched the school's two buildings to ensure no-one else was at risk. He said the school was on lockdown.
