KANE County States Attorney's Office

What KANE County States Attorney's Office does

The Kane County State's Attorney's Office is a constitutionally mandated government prosecutorial office serving Kane County, Illinois (Sixteenth Judicial Circuit). Established as the 43rd State's Attorney's office and led since 2020 by Jamie L. Mosser (re-elected 2024, first two-term female SA in county history), the office is statutorily required to represent the people of Illinois in criminal prosecutions and provide civil legal representation for county government and state officials within the jurisdiction. Operations are organized across Criminal, Civil, and Juvenile Delinquency divisions, with specialized units for Child Advocacy, Human Trafficking, Child Exploitation, and Victim Services.

The office's service portfolio spans criminal prosecution at all court levels (felony through misdemeanor, handled across three branch courts in Aurora, Elgin, and St. Charles), victim advocacy under Marsy's Law, Orders of Protection, expungement and sealing assistance, and a Homicide Support Group. Reform-oriented programs include the Collaborative Diversion Program, DUI Rehabilitative Court, First Offender Weapons Deferred Prosecution Program, and a Domestic Violence Diversion Program launched by Mosser in 2009 and expanded under her current tenure. Technology is limited to standard government infrastructure — case management, document processing, court filing, and a Laserfiche-based electronic FOIA request submission system.

The business model is government-funded: the office operates on a disclosed $9,010,052 annual budget drawn from Kane County tax appropriations, with 115 full-time and 6 part-time employees (121 total). No commercial revenue streams exist; FOIA document fees ($0.15/page after 50 free pages) generate nominal user-pay income. The primary "customers" are Kane County residents (as service recipients of prosecution, victim services, and diversion programs), county and state government entities (as civil legal clients), and the broader justice system ecosystem including over 20 collaborating local police departments. Growth is bounded by county budget appropriations rather than market dynamics, and the entity faces no commercial competition due to its constitutional monopoly on prosecutorial authority.
