SIOUX FALLS, S.D. (KELO) — A jury found two inmates guilty of assaulting two correctional officers at the South Dakota Penitentiary in 2023.

According to South Dakota Attorney General Marty Jackley, inmates Lester M. Monroe, 49, was found guilty of Attempted First Degree Murder of a Law Enforcement Officer and Aggravated Assault of a Department of Corrections Employee. Kyle Jones, 31, was also found guilty of one count of Attempted Murder.

“This was a violent assault on two of our correctional officers, including one officer who was struck more than 70 times, doing their job,” said Attorney General Jackley in a press release. “Violence in the prison will not be tolerated, and offenders will be held accountable.”

The two were convicted Friday by a Minnehaha Circuit Court Jury after a week-long trial. They will be sentenced at a later date.
