COLUMBIA, Mo. (KMIZ)

An inmate at Jefferson City Correctional Center has been charged with several felonies after authorities say he stabbed his cellmate in 2023.

Robert Zimmer, 21, was charged on Wednesday in Cole County with first-degree assault, three count of armed criminal action, having a weapon at a correctional center and violence toward an inmate.

The probable cause statement says Zimmer stabbed his cellmate with a “prison made weapon” several time to the left side of his back, thigh and hand.

The victim had multiple stab wounds and authorities found the weapon in the cell, the statement says.

Zimmer is currently serving a 15-year sentence after taking an Alford plea in 2023 in Jefferson County for first-degree burglary, stealing more than $25,000, stealing, first-degree assault and three counts of unlawful use of a weapon.
