One in custody in suspected homicide
William Davis, 53, was arrested Tuesday night and is being held on an emergency mental commitment, Janesville police Deputy Chief Dan Davis said.
He confirmed that William Davis is a suspect in the stabbing death of Joseph Hanson, 40, of Janesville who was a neighbor. The incident in an upstairs apartment at 31 S. Main St. was reported by another neighbor.
Hanson was pronounced dead at the scene Tuesday night.
Davis said William Davis was at Mercy Medical and Trauma Center, Janesville, Wednesday. Davis said he would be taken to a mental health facility once he is cleared to leave Mercy.
Two Janesville police officers responded to a call at 10:34 p.m. Tuesday, according to a press release. William Davis charged naked at the officers after they knocked on his door. Both officers used Tasers to subdue William Davis, and he was transported to Mercy.
Officers were called back to the apartment building after a neighbor found Hansonís body. Hanson was in his bed with multiple stab wounds to his torso.
Davis confirmed both Hanson and William Davis were enrolled in a Community Support Program of Rock County. The program helps people with disabilities and mental illness live independently in the community.
The Rock County Coroner is performing an autopsy to determine the cause of death.
Davis said investigators did not believe alcohol was involved in the incident, but they are investigating if William Davis was on any medication.
Davis said a knife believed to be the murder weapon was recovered.
Davis declined to say what investigators believe to be the motive and said the investigation is ongoing.
