CARPENTERSVILLE, Ill. (WGN) – A convicted sex offender and murderer has been charged with living near a day care in Carpentersville.
The Kane County State’s Attorney’s Office said 52-year-old Cayce Williams knowingly violated the Illinois Sex Offender Registration Act between March 27, 2024, and Sept. 12, 2025, by failing to register his change of address and place of employment with the Carpentersville Police Department.
Williams is a convicted child sex offender and also knowing and unlawfully lived within 500 feet of a day care facility, according to investigators.
Court documents said Williams was living on Elm Avenue in Carpentersville at the time of his arrest and had last registered as living in Chicago.
Carpentersville police officers arrested Williams on Friday, Sept. 12, 2025, and brought him to court the next day. The court ordered Williams released under a pre-trial supervision while his case is pending.
As a condition of his release, Williams must comply with the Sex Offender Registration Act and may no longer live at his previous address in Carpentersville.
He has since been charged with the following:
- Failed to Register as Sex Offender – Change of Residence Address (Class 3 felony)
- Failed to Register as Sex Offender – Place of Employment (Class 3 felony)
- Failed to Inform Agency of Information Change – Change of Residence Address (Class 3 felony)

- Child Sex Offender Residing in Day Care Zone (Class 4 Felony)
He is scheduled to appear in court at the Kane County Judicial Center on Oct. 30, 2025 at 9 a.m.
Officials said in 2006, Williams pled guilty in Kane County to first-degree murder and predatory criminal assault for the 1997 death of his then-girlfriend’s 20-month-old daughter.
Williams was sentenced to 48 years in prison and received 3,375 days credit for time severed in the Kane County Jail.
Because of state laws at the time, which have since been changed, Williams was eligible for release after service half of his sentence.
He was released from prison on parole in February of 2021 after serving 24 years.
