Charges were filed Thursday against a Purdue University engineering student accused of fatally shooting a teaching assistant at the Indiana school.
Cody Mark Cousins, 23, was charged with murdering 21-year-old Andrew F. Boldt Tuesday afternoon in a basement classroom in the electrical engineering building.
Court documents revealed Boldt sustained knife wounds as well as gunshot wounds. Police located a handgun on the ground in the classroom, according to the documents, as well as several spent shell casings and a knife.
Campus police chief John Cox said the suspect appeared to have targeted the victim, but wouldn't comment on a possible motive. He said Cousins apparently singled out Boldt, targeting no one else.
The school posted to Twitter on Tuesday that a shooting was reported on campus and students were advised to find shelter and avoid the area.
The school later confirmed an arrest was made and classes were canceled. Later that day hundreds of people gathered on Purdue's campus for a candlelight vigil, and campus officials said counseling would be offered for students and staff.
Police said Cousins surrendered outside the building following the shooting and was held in the Tippecanoe County Jail without bond.
He was due in court Thursday afternoon.
