New state law bars detention for 10- and 11-year-olds; local probation staff expect more reliance on community services

At the June 2026 Circuit Wide Committee meeting, a presenter explained recently passed state legislation that will change how juvenile detention is used in Illinois beginning July 1.

"They will no longer be able to detain 10 or 11 year olds in juvenile detention," the presenter said, adding that detention for 12-year-olds will be "severely restricted" and generally limited to very serious crimes such as first-degree murder, aggravated criminal sexual abuse, aggravated battery with a firearm and aggravated vehicular hijacking. The presenter said law enforcement detention of a 12-year-old will be time-limited for investigative purposes (approximately six hours) and that local probation and police will need to rely more heavily on community alternatives.

Committee members were told the circuit will need to coordinate with local youth service bureaus in LaSalle, Bureau and Grundy counties to expand community-based responses. The presenter specifically named the youth service bureau in LaSalle, Bureau and Grundy counties as resources to be used in lieu of detention where possible.

The presenter also described two statewide administrative developments staff expect to affect operations: a multi-year AOIC (Administrative Office of the Illinois Courts) data automation project to pull case data directly from local case-management systems, and a pending Illinois Supreme Court review of probation casework standards and core correctional practice updates that may be released in the fall.

The committee did not take formal action on the new state law during this meeting; members discussed operational implications and next steps for county coordination and data reporting.

Ending: Staff said they will continue to monitor AOIC rollout and Supreme Court guidance and coordinate with local youth services to implement alternatives to detention as the July 1 effective date approaches.
