TECUMSEH – Tecumseh state prison inmate Benjamin Gonzalez entered guilty pleas to assaulting a prison corporal on March 21 after a door was mistakenly opened.

The Nebraska Department of Corrections issued a press release saying two inmates assaulted a staff member. When an officer was escorting an inmate back to his cell, the wrong door was mistakenly opened and the second inmate, armed with a homemade weapon, stabbed the staff member multiple times.

Gonzalez, 26, is serving a 12-year sentence for assault in Platte County. Sentencing is set April 6.
