STEVENS POINT (WAOW) - A 33-year-old Plover man pleaded insanity Monday in the baseball bat beating death of his 77-year-old stepfather.
Andrew Pray pleaded not guilty and not guilty by mental disease or defect to first-degree intentional homicide in the May 26 attack of Christopher Bonnstetter, online court records said.
Prosecutors say Bonnstetter was sleeping on the floor of his living room in Plover when Pray came in, said nothing and began hitting him with an aluminum baseball bat.
No motive for the attack was clear as the stepson had "no comment" when police asked him about it as he stood outside the home he shared with his mother and stepfather, according to a criminal complaint.
Pray's mother, Jennifer Pray, told investigators she witnessed the afternoon attack and saw her son hit Bonnstetter three or four times with the bat, the complaint said.
A neighbor told police that Pray's mother told him that her son "just flipped," the complaint said.
After Pray entered the insanity plea, Portage County Circuit Judge Thomas Eagon ordered that he undergo a mental health examination to be completed by Sept. 26, court records said.
