Vernon Hills, Illinois, in Lake County, has about 27,000 residents (2024 Census Bureau estimate), and its arrests are reported to the FBI by an agency of its own. An arrest in the city leaves the same records whoever makes it: the arresting agency's report, the record of anyone held at the county jail, and, if the State's Attorney files charges, a case in the Circuit Court of Lake County. This guide says who keeps each one, what it costs and who may see it, with the arrest counts the agency reported.
This guide covers who makes arrests, how many arrests, booking and the jail, finding an arrest, copies and common questions.

Who Makes Arrests in Vernon Hills
The FBI lists Vernon Hills with an arrest reporting agency of its own, filed as Vernon Hills Police Department. It reported 334 arrests for 2025. A city is listed separately whether the officers are the city's own or the sheriff's under contract; the FBI's list does not say which.
Outside the city, the Lake County Sheriff's Office is the county agency. It reported 656 arrests for 2025.
The FBI's agency list also places these agencies in Lake County: the College of Lake County (campus police); Lake County Forest Preserve, the Round Lake Park District and the Zion Park District (other).
How Many Arrests Vernon Hills Reports
Each agency reports its arrests to the FBI by month, and the FBI publishes them on the Crime Data Explorer. These are the full-year totals, all offenses, as the FBI held them on October 8, 2026; a year with months missing or not reported is left out.
- Vernon Hills: 334 for 2025, 392 for 2024 and 226 for 2023.
Vernon Hills's 334 arrests in 2025 were down 15 percent from 392 in 2024.
Through August 2026, Vernon Hills reported 229 arrests, against 203 in the same months of 2025.
Across Lake County, the 31 agencies with all twelve months of 2025 on file reported 7,816 arrests between them.
Booking: Where People Arrested in Vernon Hills Are Held
A person kept in custody after an arrest in Vernon Hills is held at the county jail, whichever agency made the arrest, apart from the short stay some city departments' own holding cells allow; a person cited and released at the scene is not booked at all. The jail's record of each person held, with the charges, is a public record of the arrest, and the court file takes over from there.
On an average day in 2024 the jail held about 510 people, down from about 630 in 2019. Its rated capacity in 2019, the last year with a capacity figure, was 740 beds, and it ran at 85 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.
SearchSystems opened and checked the custody page of the Lake County Sheriff's Office at lakecountyil.gov/2031/Inmate-Information (page title: Inmate Information | Lake County, IL), 29 S Martin Luther King Jr Avenue, Waukegan, IL 60085, a site that blocks automated checks (HTTP 429), so open it in a browser.
That page is the place to look for someone who was booked recently; a person cited and released at the scene, or held only a few hours by a city department, will not be on it.
A sentence of more than a year is served in state prison; the Illinois Department of Corrections lists its inmates at idoc.illinois.gov/offender/inmatesearch.html.
How to Find Out About an Arrest in Vernon Hills
Whether someone was arrested in Vernon Hills, and what came of it, shows up in two places: the custody page of the Lake County Sheriff's Office described above, for anyone booked into the county jail; the case index of the Circuit Court of Lake County, which shows whether charges were filed and the next court date (the court records page SearchSystems verified is at ilsos.gov/departments/archives/databases/lake.html, phone 815-753-1807).
Illinois is one of the states that lets anyone look up another person's statewide criminal history: conviction information is public under the Uniform Conviction Information Act, through the Illinois State Police. That record shows what agencies reported to the state, which is wider than one county's court index but can lag it.
Getting a Copy of an Arrest Record in Vernon Hills
An arrest report belongs to the agency whose officer wrote it, and that agency releases it, not the court or the jail. Under the Illinois Freedom of Information Act the agency must answer within 5 business days, with one 5-day extension, and it may charge copying only after the first 50 pages.
