A 32-year-old Dolton woman has been charged with aggravated DUI and reckless homicide nearly nine months after a crash on West Diversey Avenue in Logan Square left her passenger dead. Shana Weems was arrested Tuesday, and the case traces back to a December crash that ejected 31-year-old Shanna Monique Quilter from the vehicle she was riding in.
According to FOX 32 Chicago, Weems was allegedly driving a Buick Regal with Quilter as a passenger on the 3800 block of West Diversey Avenue around 1:30 a.m. on December 8, 2025, when the sedan veered across the road. Police allege the Buick struck the rear of an eastbound semi-truck before hitting a parked car, and Quilter was ejected from the vehicle on impact. She later died from her injuries, and the Cook County Medical Examiner's Office identified her as Shanna Monique Quilter, per the same outlet's report.
Weems was taken to Advocate Illinois Masonic Medical Center in stable condition following the crash, according to CBS News. The driver of the semi-truck was uninjured and declined medical treatment. The collision forced emergency crews to shut down West Diversey Avenue between Avers and Hamlin Avenues, with the Chicago Transit Authority temporarily rerouting the No. 76 Diversey bus and traffic diverted to Fullerton and Belmont Avenues.
A Nine-Month Investigation Ends in Arrest
One week after the crash, the Chicago Police Department's Major Accidents Investigation Unit publicly requested witness accounts and surveillance footage under case reference RD# JJ514774 to reconstruct the sequence of events. The specialized unit, part of CPD's Bureau of Detectives, handles forensic crash reconstruction and speed analysis for complex or fatal collisions across the city, and also deploys Family Liaison Officers to support victims' relatives.
That effort culminated Tuesday, September 1, when the U.S. Marshals Great Lakes Regional Fugitive Task Force and Chicago police arrested Weems. CPD charged her with a felony count of involuntary aggravated DUI/accident/death, as well as reckless homicide, based on the department's charge release and the medical examiner's findings. Hoodline had first reported the crash in December, when CPD was still seeking public video and witness accounts.
What the Charges Carry Under Illinois Law
Under 625 ILCS 5/11-501(d)(1)(F) of the Illinois Vehicle Code, aggravated DUI resulting in death is a Class 2 felony punishable by 3 to 14 years in state prison, with defendants required to serve 85% of the sentence under the state's truth-in-sentencing rules, according to the Illinois General Assembly. Probation is statutorily barred in DUI fatality cases unless extraordinary circumstances are proven.
The reckless homicide charge, under 720 ILCS 5/9-3, is defined as an unintentional killing committed while operating a motor vehicle with conscious disregard of a substantial risk, and carries Class 3 felony penalties of 2 to 5 years in prison, per the Illinois General Assembly. A conviction on that count also triggers mandatory driver's license revocation.
Detention Hearing Set Under Pretrial Fairness Act
Weems has a detention hearing scheduled for Tuesday in Chicago. Because Illinois abolished cash bail statewide in September 2023 under the Pretrial Fairness Act, judges no longer set monetary bond amounts. Instead, prosecutors seeking to hold Weems before trial must prove by clear and convincing evidence that she poses a specific public safety threat or flight risk, according to Illinois Legal Aid Online.
A Corridor With a History of Deadly Crashes
Citywide, Chicago recorded 136 traffic-related fatalities in 2023, a 27 percent decrease from 2021, with vehicle occupants accounting for 80 of those deaths, according to Chicago Department of Transportation data cited by Justia. But West Diversey Avenue itself has been flagged by CDOT safety analyses as a higher-risk corridor, recording 1.32 crash fatalities or severe incidents per 100,000 residents.
The stretch has seen fatal incidents before. In July 2022, a 38-year-old pedestrian was struck and killed on the 4500 block of West Diversey Avenue, roughly seven blocks west of where Quilter died, as reported by Streetsblog Chicago. Weems's case now moves from months of forensic crash reconstruction into active criminal prosecution, with Tuesday's detention hearing marking the next step in the process.
