One person died in a shooting today on the campus of Purdue University in West Lafayette, Ind., and one person is in custody.
Police said the victim was a male and they were trying to identify him.
The suspect is not cooperating at all with authorities, according to campus Police Chief John Cox. They are still trying to obtain the suspect's identity as well.
Purdue campus police said the shooting occurred in the basement area of the electrical engineering building this afternoon.
The suspect was apprehended moments after the shooting as he ran outside and was caught by West Lafayette, Ind., police, Cox said at a news conference today.
Twenty to 25 campus police officers responded to the electrical engineering building within two minutes, Cox said. He noted the campus police and city police trained together for active shooter situations.
The shooting triggered a "shelter in place" text message alert for the rest of campus, students told ABC news. Classes were in session when the shooting occurred, Cox said.
Police said there was no ongoing threat to the university. The campus was reopened around 1:30 p.m., though the Electrical Engineering building remains closed.
"I'm off campus but near the (electrical engineering) building. You can hear the emergency sirens and there have been 30 to 40 cop cars surrounding the EE building over the last 30 minutes," Daniel Hatfield said.
Hatfield said that police searched other buildings in addition to the engineering building. He said students and teachers are taking the lockdown "very seriously."
Kevin Brown said he was in lockdown at the business school, nearly three-quarters of a mile away from the engineering building and he has not yet been able to get in touch with friends in the engineering building.
