WEST LAFAYETTE, Ind. — One person was killed inside a Purdue University classroom today by a gunman who surrendered to a police officer within minutes of the attack, officials said.

Purdue Police Chief John Cox said the man appeared to have targeted the victim, also a male, around noon in a basement classroom of the Electrical Engineering Building. Cox said he didn’t attack anyone else.

“The individual entered the facility and took the actions that he took, and then immediately left the facility without any other interaction that we’re aware of,” Cox said.

The suspect gave himself up to a West Lafayette police officer outside the building on the 40,000-student campus, he said.

Cox and Purdue Provost Tim Sands told reporters during an afternoon news conference that they had not yet confirmed the identities of either the suspected gunman or the victim.

Cox said the man arrested wasn’t immediately cooperating with investigators.
