Prosecutors say a man beat an elderly Waukegan Public Schools crossing guard until he was unconscious and stomped on his head in an unprovoked attack in Waukegan.

Clay C. Jones, 41, of Waukegan, was charged with one count of aggravated battery of a senior citizen and two counts of battery causing bodily harm.

A 69-year-old crossing guard, who is employed by Waukegan Public School, was working on Wednesday.

Lake County Assistant State’s Attorney Dino Katris said the crossing guard was stationed at Washington Street and Lewis Avenue in Waukegan.

A gas station attendant at the Mobil gas station, which is at the same intersection, looked outside and noticed an attack.

The crossing guard was on the ground while a man, later identified as Jones, was stomping on the crossing guard’s face, Katris said during a bond hearing.

The victim was knocked unconscious and paramedics transported him to Vista Medical Center East in Waukegan.

He sustained a swollen face and abrasions and had to be evaluated for a concussion.

Katris said the attack on the guard was unprovoked and a witness identified Jones as the suspect.

While officers were investigating the case, they learned that Jones had attacked a homeless person in front of a nearby store earlier in the morning.

Lake County Judge Theodore Potkonjak ordered Jones held on a $250,000 bond and ordered him to have no contact with the victims.

Jones remains held in the Lake County Jail and would need to post $25,000 cash in order to be released.

Jones is scheduled to appear in court again on November 3 for a preliminary hearing.
