LAFAYETTE, Ind. (AP) – Prosecutors have filed murder charges against a Purdue University student in the shooting of a fellow student in a classroom.

The Tippecanoe County prosecutor's office filed the charges Thursday against 23-year-old Cody Cousins shortly before a scheduled initial court hearing.

The court documents say 21-year-old Andrew Boldt of West Bend, Wis., suffered both gunshot and knife wounds when he was fatally attacked Tuesday in Purdue's Electrical Engineering Building.

The charging document says several other people were in the classroom and witnessed the attack, but it doesn't give any possible motive for the attack.

Police say an officer spotted Cousins with blood on his hands and clothes soon after the attack and arrested him without incident.

Boldt's funeral is scheduled for Tuesday in his Wisconsin hometown.
