DeKalb County Jail Mugshots

DeKalb County jail mugshots are maintained by the sheriff's office in Sycamore, Illinois. The county has about 100,420 residents and sits in the northern part of the state, west of the Chicago suburbs. Every arrest that goes through the DeKalb County Jail results in a booking record with a mugshot photograph. You can search for these records by contacting the sheriff, making a FOIA request, or using state databases that track arrest and inmate data for all of Illinois. Below is a full guide to finding jail mugshots from DeKalb County.

DeKalb County Sheriff's Office

The DeKalb County Sheriff's Office runs the county jail and keeps all booking records for the area. The main office is at 150 N. Main Street in Sycamore, IL 60178. You can call (815) 895-2155 for questions about inmates, booking data, or how to request records. When a person is brought to the DeKalb County Jail, staff photograph them, record their charges, and enter all personal information into the booking system. Each booking gets a unique number that ties together the mugshot, charges, and court schedule.

DeKalb County includes the city of DeKalb, home to Northern Illinois University, along with Sycamore, Genoa, Sandwich, Cortland, and several smaller towns. The city of DeKalb itself has a population over 40,000 and generates a significant portion of the county's arrests. Local police departments across the county bring arrested individuals to the county jail for processing. This means the sheriff's office has the central record for virtually every jail mugshot in DeKalb County, regardless of which police department made the arrest.

How to Search DeKalb County Mugshots

The quickest way to find a jail mugshot from DeKalb County is to call the sheriff's office. Dial (815) 895-2155 and give them a name. Staff can check the system and tell you if that person has been booked. They will also confirm if the individual is still in custody or has been released. For in-person requests, visit 150 N. Main Street in Sycamore during business hours. Have the person's full name ready, and an arrest date if you know it.

State databases are another useful tool. The IDOC inmate search shows people who were convicted in DeKalb County and transferred to a state prison. The tool is free. You can search by name and see the inmate's facility, offense, and release date. It has state-level photos but not the original county booking mugshot. For that, you need to go through the DeKalb County Sheriff directly.

The Illinois State Police Bureau of Identification holds criminal history records from across the state, including data from DeKalb County arrests. A Conviction Information Request gets you formal conviction records. This is more thorough than a mugshot lookup and is often used for legal or official purposes.

Illinois Law on DeKalb County Jail Mugshots

Illinois law at 5 ILCS 140/2.15 requires law enforcement agencies to release arrest information within 72 hours of booking. That includes the person's name, age, address, charges, photograph, and the time and place of the arrest. DeKalb County is required to follow this rule just like every other county in the state. If you request booking information shortly after an arrest, the sheriff's office must give it to you within that window.

There are restrictions on how agencies share mugshots. The law prohibits posting booking photos on social media for low-level offenses. Class B and C misdemeanors, petty offenses, and civil violations all fall under this ban. The only exceptions are for fugitives and missing persons. The mugshot still exists as part of the DeKalb County booking record; the sheriff simply cannot distribute it through social media for these minor charges. This prevents low-level arrests from being amplified through government social media pages.

Conviction records are handled separately under the Uniform Conviction Information Act (20 ILCS 2635). The Illinois State Police must make these records available to anyone who asks. If a DeKalb County arrest ended in a conviction, that data is in the statewide database. You request it through the Bureau of Identification using their standard form.

Note: The 72-hour rule applies to basic arrest data only and does not cover court records or ongoing investigation details.

Requesting DeKalb County Booking Records

Filing a FOIA request is the official way to get a copy of a jail mugshot or booking record from DeKalb County. Under the Illinois Freedom of Information Act, every person has the right to request public records from a government agency. To start, write a letter or email asking for the specific records you need. Direct it to the DeKalb County Sheriff's Office at 150 N. Main Street, Sycamore, IL 60178. Include the full name of the person, date of birth if available, and the arrest date or a date range.

The office has five business days to respond. They can take five more days if the request is complex. Under the State Records Act (5 ILCS 160), they can only charge for the actual cost of making copies. Labor fees are not allowed. If they deny the request, the Illinois Attorney General's Public Access Counselor can review the decision. This appeals process is free and gives you a formal channel to challenge a denial from the DeKalb County Sheriff's Office.

• Address the request to the DeKalb County Sheriff's Office in Sycamore
• State that you are making the request under the Illinois FOIA
• Include the person's full name and date of birth
• Provide the arrest date or range of dates
• Ask for the booking record and mugshot photograph
• Call (815) 895-2155 to ask if email requests are accepted

Mugshot Privacy in DeKalb County

Illinois law protects people from websites that exploit booking photos. Under 815 ILCS 505/2QQQ, it is illegal for any website to charge a fee to remove a person's mugshot. If your DeKalb County booking photo shows up on a site that demands payment for removal, that site is violating the Consumer Fraud and Deceptive Business Practices Act. The Illinois Attorney General can take enforcement action. Individuals can also file a lawsuit and claim $100 per day for each day that inaccurate information remains on the site.

For people who want a more permanent solution, expungement or sealing may be an option. If your DeKalb County arrest ended without a conviction, or if you completed a sentence and meet the eligibility requirements, you can ask a court to seal or erase the record. The Office of the State Appellate Defender publishes a free guide on how expungement and sealing work in Illinois. Once a judge grants the order, the DeKalb County jail mugshot and booking record are removed from public access or destroyed entirely.
