Prosecutors say alcohol a factor in beating death of Campton Hills woman

Bond set at $300k for Thomas Summerwill

CAMPTON HILLS – Prosecutors allege Thomas Summerwill, 21, was experiencing “alcohol impairment” when he beat his mother, Mary Summerwill, 53, to death with a baseball bat on March 24.

Kane County prosecutors allege that the morning of March 24, Summerwill awoke in his Campton Hills home 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 it, not realizing the person was his mother, Mary Summerwill, who died as a result of the blunt force trauma,” stated a news release from the Kane County State’s Attorney’s Office.

Prosecutors assert that Thomas Summerwill’s belief was not reasonable, because of his alcohol impairment, the release stated. Prosecutors would not say what his blood alcohol content was, other than it is specific evidence that will come out as the court case proceeds.

Summerwill was charged with two counts of second degree murder May 13 and bond was set at $300,000.

According to the Campton Hillls police department, on the morning of March 24, both local and sheriff’s police officers responded to a 911 call at Summerwill’s home on the 40W600 block of Willowbrook Drive and found Mary Summerwill, who was subsequently transported to Northwestern Medicine Delnor Hospital in Geneva, where she died.The coroner’s office later determined she most likely died of cranial injuries from a baseball bat attack.

According to Liam Dixon, Thomas Summerwill’s attorney, had just returned from a trip to Europe.

“She was in his bedroom and he thought it was an intruder in his room in the dark.” As to why his mother was in his bedroom, Dixon said, “Maybe she was checking on him.”

Dixon said the charges against Summerwill are based on the belief that his actions were intentional and his explanation of why he struck his mother repeatedly was unreasonable. Dixon said his client would be posting $30,000 bail or 10 percent of the bond that was set. Johnson set Summerwill’s next court date for May 23.

Speaking after bond court Tuesday, Dixon said Thomas Summerwill is supported by his father, Jeffrey Summerwill, his brother Ryan Summerwill, as well as Mary Summerwill’s father, brothers and sisters.

“It’s devastating,” Dixon said of the circumstances of Mary Summerwill’s death on the family.
