PEKIN — A young Morton man will go to prison for up to 30 years for inflicting severe injuries on his 18-month-old niece while babysitting her last summer.

Kahlus Adams, 21, pleaded guilty Tuesday to three counts of aggravated battery to a child causing great bodily harm, crimes that left his victim with a leg broken in half, a broken arm and a bleeding brain.

He committed them in a violent outburst when the toddler wouldn’t stop crying as he watched her and her siblings for their parents on Aug. 11, 2017, in his apartment at 110 W. Lakeland Road, a prosecutor’s court affidavit stated.

While each count carries six to 30 years behind bars, Adams will serve the terms concurrently under a plea agreement but must serve at least 85 percent of them. He’ll be sentenced on Nov. 5.

The child was hospitalized for several days with the injuries that also included facial abrasions and bruises, the affidavit stated.

Adams and his wife picked the children up in the early morning. By mid-morning the parents were notified that their young daughter was at a Peoria hospital. Adams’ wife was not home at the time of the assault, the affidavit stated.

After a doctor told police the girl’s injuries were far too severe to have been caused by falling off of a couch, as Adams and his wife first claimed, Adams acknowledged he caused them, the affidavit stated.

He said he first threw a filled sippy cup at the child’s face, then picked her up by her arms and feet, swung her around and threw her, causing her head to strike a wall and a freezer, the affidavit stated.

When the girl began “shaking severely,” Adams grabbed her leg and twisted it until her femur was broken in half, the affidavit stated.

Adams, who had no prior criminal record in Tazewell County, posted a $10,000 cash bond for his release after he was charged. County jail and court records did not show him in custody Wednesday.
