A Campton Hills man accused of beating his mother to death with a memorabilia baseball bat has been sentenced to probation in a recent plea deal with the Kane County State's Attorney's Office.

Thomas Summerwill, who was 21 at the time of the March 2019 incident, had been charged with second degree murder in the death of 53 year-old Mary Summerwill. He pleaded guilty to involuntary manslaughter as part of the deal.

Kane County State's Attorney Spokesman Christopher Nelson says Summerwill will be on probation for four years, be required to complete 200 hours of community service, and will attend various treatments such as substance abuse counseling. Summerwill has been free on bond since being charged.

Prosecutors said that Summerwill believed that he was acting in self-defense on March 24, 2019 when he hit his mother in the head multiple times with a memorabilia baseball bat resulting in her death in a home in Campton Hills. Prosecutors said that the belief of self defense was unreasonable because of Summerwill's alcohol impairment at the time.

Summerwill's lawyer had said he may have been suffering from jetlag when he thought his mother was an intruder and did not realize it was her. Summerwill was said to have had a good relationship with his mother and had the support of the family who was devastated from a horrible accident, according to the attorney.
