Aurora Burglar Swipes Deputy's AR-15 From Squad Car, Sheriff Kept It Quiet for Days

A rifle belonging to the Kane County Sheriff's Office was stolen out of a deputy's squad car early Tuesday morning while it sat parked outside his home in Aurora, and the department waited nearly two full days before telling the public. The missing weapon, a county-owned Aero Precision AR-15, has not been recovered, and the sheriff's office says an internal review is now underway to determine whether department policy was followed.

According to WSPYnews, the theft happened during the early morning hours Tuesday, with the rifle taken from the squad car while it was parked at the deputy's Aurora residence. The Kane County Sheriff's Office provided a photograph of the squad car and confirmed the AR-15 was reported stolen, but the department did not make the theft public until roughly 6:45 p.m. Thursday. Officials have called the theft an isolated incident.

The exact model and date of the burglary were detailed by Shaw Local, which reported the two-day gap between the burglary and the public announcement. The sheriff's office has said that releasing more information earlier could have jeopardized active investigative leads and efforts to identify a suspect, and it maintains it cannot disclose much more while the investigation remains active.

Who Locked What, and When

Investigators are still working to develop leads and potential suspects, per the sheriff's office. Meanwhile, the department's Office of Professional Standards is reviewing whether sheriff's office policies and procedures were properly followed when it comes to securing the weapon inside the vehicle, according to the same WSPYnews report.

That internal question lands amid a statewide shift in how Illinois treats firearm storage. Under Senate Bill 8, the state's Safe Gun Storage Act that took effect in July 2025, gun owners are required to keep firearms in locked containers inaccessible to unauthorized people wherever they're stored, including inside vehicles, as reported by WGLT. Violations of that law can carry civil fines of up to $10,000 depending on whether the weapon is accessed by an unauthorized person or used in a crime. The Kane County deputy's rifle theft has drawn questions locally about whether law enforcement personnel are held to the same storage standard as private gun owners, a tension flagged directly in reporting on the incident.

A Pattern Playing Out Across Illinois

Gun thefts from vehicles are not an isolated Kane County problem. Nationally, a firearm is stolen from a vehicle roughly once every nine minutes, according to a 2026 analysis from Everytown Research & Policy, which found that vehicle break-ins have overtaken residential burglaries as the leading source of stolen crime guns. In Illinois specifically, Bureau of Alcohol, Tobacco, Firearms and Explosives data cited by Chicago Patch shows an average of 4,265 firearms reported stolen from private citizens each year statewide, with thefts from vehicles and private property accounting for more than 95 percent of all stolen crime guns nationally.

State law has also tightened around reporting timelines. Illinois statutory provisions that took effect this year require firearm owners to report a lost or stolen weapon to local law enforcement within 48 hours of discovery, down from a previous 72-hour window, according to Capitol News Illinois. Separately, under Public Act 104-0030, law enforcement agencies statewide are now required to trace every recovered or crime-involved firearm through the ATF's eTrace system and share that trace data statewide, per Robbins Schwartz — a requirement that would apply if the stolen AR-15 is ever recovered in connection with a crime.

Aurora's Recent History With Stolen Guns

Stolen firearms turning up in local incidents is not new to Aurora. In February 2026, Aurora police and Kane County Sheriff's deputies arrested two 17-year-old suspects following a vehicle pursuit in the city, recovering a loaded .40-caliber handgun that had previously been reported stolen from another municipality, as reported by the Daily Herald.

The Kane County Sheriff's Office is headquartered at the Adult Justice Center in St. Charles and holds primary jurisdiction over unincorporated parts of the county, though deputies commonly live in and park take-home squad vehicles at residences in neighboring cities like Aurora. For now, the stolen rifle remains unaccounted for, and the sheriff's office has not said whether any suspect has been identified or whether charges are anticipated once the investigation concludes.
