During an interview following his arrest, the suspect told police that he was friends with one of the victims, a 23-year-old man named Jacob D. Schupbach, and had gone to Schupbach's house to smoke
marijuana. According to the suspect, he became
paranoid that the drugs Schupbach gave him were laced with an unknown
narcotic, after which he retrieved a knife from the kitchen and fatally stabbed Schupbach, along with Schupbach's 63-year-old mother, Ramona. Additionally, witnesses reported seeing the assailant enter a black
Chevrolet Silverado and run over Jacob Schupbach before following him back into the house. After exiting the home, the assailant fatally stabbed Jay P. Larson, a 49-year-old
postal worker, whom the assailant then ran over twice as he fled in his
pickup truck. At a nearby residence, the assailant stabbed a woman near her left eye as she opened the door to let their
pit bull out, then wounded her adult son and daughter. The assailant fled after the woman's son struck him with a syrup bottle. The assailant then entered the unlocked back door of another residence on the same street, where three girls on
spring break had been watching movies in the basement. After asking the girls where a gun was located and yelling
expletives at them, the assailant attacked all three with an
aluminum softball bat he had retrieved from the kitchen. One of the girls, 15-year-old Jenna A. Newcomb, was fatally injured before the assailant eventually fled the home. The other girls, aged 15 and 14, survived. According to Newcomb's mother, she died protecting her sister and friend from further harm. The attacks continued in another part of
Winnebago County, where the assailant broke into a woman's home through a window, chased her into her yard, and attacked her with his knife, causing stab wounds to her hands and face. He then injured a man who was driving by and stopped to intervene; The assailant also attempted to steal the man's
Jeep. As the assailant began attacking the man, police arrived and took him into custody, with a deputy sustaining a stab wound to his hand in the process. ==Victims==
