Investigators believe a Waupun man killed his grandmother because he was upset she spoke to police about his drug use causing him to lose custody of his children. Gregory Spittel made his initial Fond du Lac court appearance Tuesday on 12 additional charges including first degree intentional homicide in the death of 75 year old Carol Foreman. According to a criminal complaint on August 23 Spittel assaulted Foreman in the basement of his Waupun home, likely striking her in the head with his fist causing her to strike her head against the concrete floor. Spittel continued to strike her in the head after she had fallen according to the complaint. According to the complaint Spittel removed his blood soaked pants and t-shirt, locked his dog upstairs and went to his bedroom to sleep. Detectives believe Spittel caused damage to the kitchen of the home after the assault to cover up the crime suggesting someone else assaulted and murdered his grandmother. Bail was set at $1 million cash. A preliminary hearing is scheduled for January 2.
