A Campton Hills man plead guilty in his mother’s 2019 death Monday.
Thomas W. Summerwill, 23, agreed to four years of probation and 200 hours of community service in exchange for a guilty plea of involuntary manslaughter in the March 2019 beating death of his mother, 53-year-old Mary B. Summerwill, Kane County State’s Attorney Jamie L. Mosser said.
In addition to the probationary period and community service work, Summerwill cannot consume alcohol and must wear an alcohol-monitoring device for the duration of his probation, Mosser said. He also must undergo intensive alcohol and grief counseling, as well as a psychological evaluation.
On the morning of March 24, 2019, Summerwill was asleep when he awoke to what he believed was an intruder in his bedroom, not realizing it was his mother, Kane County Assistant State’s Attorney Greg Sams said in court. He grabbed a baseball bat and struck Mary Summerwill multiple times in the head.
An investigation revealed that Summerwill’s blood-alcohol concentration was .270 — over five times normal levels — and his blood contained tetrahydrocannabinol (THC) metabolites.
