Daniel A. Lawniczak, 21, of McHenry.

A McHenry man was sentenced to five years in prison for beating a 60-year-old man at a Spring Grove bar, leaving him seriously injured.

Daniel A. Lawniczak, 21, of the 300 block of Burr Avenue in unincorporated McHenry, pleaded guilty during a negotiated plea to one count of aggravated battery, a Class 3 felony. He was originally indicted on seven counts of aggravated battery.

Prosecutors said that Lawniczak was at the Brick and Ivy Sport Tavern in Spring Grove on August 23, 2019.

He kicked and struck the head, chest and midsection of a man, causing bodily harm, prosecutors said.

The attack caused the victim, who was 60 years old, to sustain serious injuries requiring hospitalization.

McHenry County Judge Robert Wilbrandt sentenced to Lawniczak to five years in the Illinois Department of Corrections, but he will only have to serve 50% of the sentence, according to Illinois truth-in-sentencing guidelines.

Lawniczak was ordered to one year of mandatory supervised release following his prison sentence. He was required to pay $549 in court assessments but those were waived after he requested a fee waiver, court records show.

The case was investigated by the Spring Grove Police Department and prosecuted by Assistant State’s Attorney Mary Ann Scholl of the McHenry County State’s Attorney’s Office.
