WEST LAFAYETTE, Ind. — A Purdue University engineering student opened fire inside a basement classroom Tuesday, killing a teaching assistant and prompting officials to put the campus on lockdown, police and the university said.
Cody Cousins, who is believed to have targeted Andrew Boldt inside the Electrical Engineering Building, surrendered to a police officer within minutes of the attack, Purdue Police Chief John Cox said.
Investigators were trying to determine a motive for the shooting, which happened around noon on the campus in West Lafayette, about 60 miles northwest of Indianapolis. No one else was injured.
"This appears to be an isolated and intentional act," Cox said.
Boldt, a 21-year-old senior and teaching assistant from West Bend, Wis., died at the scene. Cousins, 23, who according to police has addresses listed both in Warsaw, Ind., and Centerville, Ohio, was being held on a preliminary charge of murder Tuesday night at the Tippecanoe County Jail.
Students described a chaotic scene on the campus. Sophomore Nick Wieland told the Journal & Courier that he was in a basement classroom adjacent to the one where the shooting occurred.
"I heard a couple (shots) and then I heard a man scream," Wieland said. "Then the last few kind of trailed off as I got under my desk. . (I was) just very scared. That's what I felt the entire time."
Julissa Martinez, a freshman in nursing, told The Associated Press that she was in a psychology class on another part of the campus when she received the text alert from university officials telling students to seek shelter.
She said her professor briefly kept teaching, then stopped lecturing so that students could contact people to let them know they were safe.
"He tried to get everything under control because people were freaking out," Martinez said, adding that students were nervous because there was a lot of speculation about the severity of the situation.
