UPDATE: Knysz Dead After Taken Off Life Support

Posted: Updated:

The man who killed Trooper Paul Butterfield is dead.

The State Department of Corrections says Eric Knysz was taken off life support at 10:30 Thursday morning.

Knysz was hospitalized after trying to hang himself at a Jackson prison on Monday.

He was declared brain dead, and was kept of life support so his organs could be donated.

Knysz was sentenced to life in prison for the murder of Trooper Butterfield in September.
