Campton Hill Man Charged With Murdering His Mother — By Mistake

A Campton Hills man faces criminal charges in the beating death of his mother, 53-year-old Mary B. Summerwill, seven weeks ago.

The Kane County State’s Attorney’s Office has charged 21-year-old Thomas W. Summerwill with two counts of second-degree murder, a Class 1 felony, according to an SAO news release.

Kane County prosecutors allege that the morning of March 24, 2019, Summerwill awoke to what he believed was an intruder in his bedroom.

Acting in what he believed was the defense of himself or his property, Summerwill grabbed a baseball bat and struck the person multiple times in the head with the bat, not realizing the person was his mother, Mary Summerwill, who died as a result of the blunt force trauma.

Prosecutors allege that Thomas Summerwill’s belief was not reasonable because of his alcohol impairment.

Thomas Summerwill surrendered May 13 to Campton Hills police, and appeared Tuesday in Kane County bond court.

Associate Judge Keith Johnson set his bail at $300,000 with 10 percent ($30,000) to apply for bond. Johnson set Summerwill’s next court appearance for 9 a.m. May 23, 2019, in Courtroom 313 at the Kane County Judicial Center.

“Thanks to Campton Hills Police Chief Steve Millar and his team, as well as the Kane County Major Crimes Task Force, for their work in this investigation,” Kane County State’s Attorney Joe McMahon said.

The charges against Summerwill are not proof of guilt. Summerwill is presumed innocent and is entitled to a fair trial in which it is the state’s burden to prove guilt beyond a reasonable doubt.
