A person was shot and killed in Purdue University's electrical engineering building on Tuesday by a gunman who later surrendered to a police officer outside, the Indiana school's police chief told reporters.
Both the suspect and the victim were males, Purdue Police Chief John Cox said, but their names weren't immediately released, CNN reported.
Students throughout the campus were asked to stay indoors when the shooting occurred at about noon. With about 30,000 undergraduates in West Lafayette, students didn't come out until police gave the all-clear a little more than an hour later.
The suspect seemed to just have one target in mind, Cox said. After the shooting, he left the building and was arrested by a city officer, CNN reported.
"This individual seemed to have had intentions for the decedent," he said.
According to CNN, no information about a motive was released. Cox said the suspect made no statement to investigators and was offering "little to no cooperation."
Students were in the building's lecture hall for a noon economics class when the shooting happened in another room, Hook, a Purdue sophomore, told CNN. Shouting was heard from outside the hall, behind and to the left of the instructor.
"Originally, I just thought it was just people being loud," Hook, 20, said. "When I heard (shouting) the second time, I thought something was probably going on."
No gunfire was heard by Hook. A minute later, someone entered the hall and told everyone to leave the building without mentioning the shooting, Hook said.
Hook said he saw police outside the building while walking back to his apartment but didn't see any arrest, CNN reported.
Students were sent text messages by the school about the shooting, asking them to take shelter where they were.
That request was lifted by 1:30 p.m., though the electrical engineering building still was closed so police could investigate, school spokeswoman Liz Evans said.
"The rest of campus is open" and classes were under way, Evans said.
According to CNN, "Purdue student Brad Glusvewski told CNN that the university warned students of the reported shooting by text message around 12:20 p.m. ET. Glusvewski, 24, said he and about 15 other people stayed inside the on-campus building during the alert."
