LAFAYETTE, Ind. (AP): A court official says the man accused of the fatal shooting and stabbing of a fellow Purdue University student has pleaded guilty to a murder charge.

Cody Cousins of Warsaw made the plea during a Tippecanoe County court hearing Thursday. He has been jailed since his arrest soon after the Jan. 21 attack that killed 21-year-old Andrew Boldt of West Bend, Wisconsin, inside a Purdue classroom.

Cousins' defense attorney had said in May he would pursue an insanity defense. Tippecanoe Superior Court bailiff Brenda Rody says the judge will decide the issue of Cousins' mental state during a sentencing hearing set for Sept. 19.

Cousins and Boldt were both electrical engineering students at the time.
