Daniel J. Happ entered a guilty plea to charges for beating a woman repeatedly over the head with a hammer, sexually assaulting her 8-year-old daughter, and stabbing her dog.
A northern Illinois man has pleaded guilty but mentally ill to beating a woman in the face with a hammer, raping a child and stabbing a dog in a rampage at a suburban Chicago home.
Twenty-nine-year-old Daniel J. Happ of Carpentersville entered the plea Friday to charges of attempted murder, sexual assault and animal cruelty. He is to be sentenced Oct. 15 in Kane County court. He faces between 12 and 93 years in prison.
The Kane County State's Attorney's Office says Happ knew the woman. Prosecutors say he was visiting her at her boyfriend's home in March of last year when he became violent, attacking her and sexually assaulting the boyfriend's 8-year-old daughter.
Happ is also accused of stabbing the family dog multiple times with a kitchen knife.
