A magistrate entered a not guilty plea for a Purdue University student charged with murder in the shooting of another student in a classroom.

Twenty-three-year-old Cody Cousins of Warsaw appeared at a hearing Thursday at the Tippecanoe County Jail to face a charge of murder in the death of 21-year-old Andrew Boldt of West Bend, Wis.

Court documents say Boldt suffered both gunshot and knife wounds when he was fatally attacked shortly before 12:30 p.m. Tuesday in Purdue's Electrical Engineering Building.

Prosecutors asked that Cousins be held without bond and defense attorney Robert Gevers II didn't contest that, so Magistrate Sean Persin ordered that Cousins be held.

Cousins sat composed with his hands on his lap for most of the 10-minute hearing, attended by three unidentified family members.
