Jonathan P. Clary, 33, of Waukegan.

A Waukegan man was arrested after he allegedly attacked his mother, who is over 60 years old, with a sledgehammer in Waukegan, leaving her with serious injuries.

Jonathan P. Clary, 33, of Waukegan, was charged with aggravated battery causing great bodily harm, aggravated battery on a victim over 60 and aggravated domestic battery.

Lake County Assistant State’s Attorney Lillian Lewis said officers responded on Tuesday to a residence in Waukegan.

The husband of the victim spoke on the phone with his wife, who did not sound right so he came home to check on her.

The man observed his wife laying in their bed suffering from significant injuries, Lewis said.

The man told officers that his wife appeared to have been struck with a sledgehammer as she had been laying in the bed.

The victim told police she had an argument with her son and he attacked her, Lewis said.

Police arrested Clary after finding the sledgehammer used in the attack. It was bloody and sitting next to bloody clothes, which belonged to the victim.

Officers also observed blood on the walls and a couch along with a broken window.

Clary had a knife and a sword, which were also bloody, on his person when officers took him into custody, Lewis said.

The victim was transported by ambulance to the hospital and determined to be suffering from a brain bleed and concussion. Both of her eyes had been swollen shut.

Lake County Judge Theodore Potkonjak ordered Clary held on a $350,000 bond.

Clary remains held in the Lake County Jail and would need to post $35,000 cash in order to be released.

A preliminary hearing is scheduled for November 23.
