Man charged after allegedly stabbing sleeping passenger on Chicago Blue Line, prosecutors say he filmed the attack
CHICAGO — A Chicago man faces first-degree murder charges after allegedly fatally stabbing a sleeping passenger on a CTA Blue Line train and recording the unprovoked attack on his cellphone early Jan. 10, prosecutors said.
- Victim: 37-year-old Dominique Pollion was found bleeding on a Blue Line train and later pronounced dead at Northwestern Memorial Hospital.
- Suspect: 40-year-old Demetrius Thurman faces one count of first-degree murder; prosecutors say he filmed the assault and aftermath.
- Evidence: CTA surveillance, phone footage, witness statements and body-worn camera video helped identify and arrest the suspect quickly.
- Court: Thurman made his first appearance Jan. 13; the case proceeds with a next hearing set for Jan. 20, 2026.
Incident details
According to court records and police reports reviewed by local media, the assault occurred about 2:17 a.m. on Saturday, Jan. 10, near the Clark/Lake station in the Loop. Dominique Pollion had been asleep on the Blue Line train for almost an hour and had no known interaction with the suspect before the attack, prosecutors said. (Sources: Fox News, FOX 32 Chicago.)
How prosecutors say the attack unfolded
Prosecutors allege Thurman approached Pollion from behind, began recording on his phone and stabbed him twice — once in the chest near the heart and once in the abdomen — using a knife with a bright-orange handle. Pollion awoke, screamed, attempted to back away down the aisle and then collapsed. After the assault, Thurman walked to another car and later exited at Clark/Lake. CTA surveillance cameras captured the assault and the suspect’s face. (Sources: CBS News Chicago, Fox News.)
Thurman’s actions during and after the alleged attack
Prosecutors told a judge that Thurman recorded the stabbing on his cellphone and then pointed the camera at himself, capturing his face. From outside the train at Clark/Lake, he allegedly recorded again, turned the camera on himself and said,
“somebody got his ass,”
before fleeing the station. Police later recovered Thurman’s phone under a search warrant; authorities say it contained the stabbing video, photos of sleeping passengers and other recordings. (Sources: ABC7 Chicago, FOX 32 Chicago.)
How police identified and arrested Thurman
Investigators used multiple tools: they ran CTA surveillance images through the Illinois Secretary of State’s facial recognition program and circulated images widely. A Chicago police officer who had previously encountered a man sleeping on a Blue Line train — captured on body-worn camera when the man provided a driver’s license — recognized Thurman from the police bulletin. Thurman’s cousin also identified him from the surveillance footage. Thurman was arrested on Sunday, Jan. 11, at 210 S. Canal St. in the West Loop wearing the same clothes seen in the video and carrying the phone with alleged evidence. After being taken into custody, prosecutors say Thurman admitted the stabbing.

Charges, court proceedings and prosecutors’ account
Thurman is charged with one count of first-degree murder. He made his first court appearance on Tuesday, Jan. 13, 2026, where prosecutors described the cellphone recordings and the surveillance evidence that led to his arrest. His next court date is scheduled for Jan. 20, 2026. Investigators and prosecutors described a strong chain of physical and digital evidence — CTA surveillance video showing the attack, phone footage recovered under warrant, witness statements and prior body-worn camera footage — that moved the case quickly from investigation to arrest and charges.

Background on Thurman
Court records indicate Thurman has prior encounters with the law, including supervision for disorderly conduct in 2014, a DUI in 2017, and a 2023 traffic arrest that resulted in supervision after a guilty plea. Prosecutors say the new digital and video evidence is central to pursuing the first-degree murder charge in the Blue Line case. (Sources: Fox News, FOX 32 Chicago.)
How witnesses and CTA staff responded
After the train stopped, a passenger alerted platform security. Officers on the platform found Pollion wearing multiple layers that initially concealed his stab wounds. Medical personnel transported him to Northwestern Memorial Hospital, where he was pronounced dead. CTA surveillance footage was instrumental in reconstructing the sequence of events and the suspect’s movements through the train and station. (Sources: CBS News Chicago, FOX 32 Chicago.)
CTA video recording murder and public safety questions
The case raises urgent questions about safety on public transit and how digital evidence is used in investigations. The alleged CTA video recording murder and the phone footage reportedly taken by Thurman show how surveillance and digital forensics can speed investigations and hold suspects accountable — while also renewing debate about station and train security late at night and the balance between surveillance and civil liberties.

Implications for Paso Robles, California
Contextual note: coverage of a violent, widely reported transit attack in Chicago can have ripple effects in other communities. Below are practical implications and recommendations for Paso Robles leaders and residents.
Economic impact: A high-profile transit attack can alter travel behavior and reduce short-term regional travel or overnight stays; local tourism and hospitality businesses should monitor bookings and be ready to reassure visitors.
Political consequences: The case highlights law-enforcement tools and interagency cooperation. Local leaders may face calls to support enhanced public-safety measures, invest in victim services and debate facial-recognition use versus civil liberties. (Sources: Fox News, CBS News Chicago.)
Social effects and cultural relevance: Random violence on mass transit can heighten commuter anxiety. Community and faith leaders can help by reminding residents of safety steps and supporting those affected by national crime coverage.
Practical applications for residents:
- Travel safety: Sit where you can be seen, keep exits in mind and avoid isolated cars late at night.
- Reporting: If you see suspicious behavior at transit shelters, call local authorities or transit security immediately.
- Support services: Ensure local victim services and mental-health resources are available for residents affected by high-profile incidents.
- Policy discussion: Officials may consider reviewing station staffing, lighting, surveillance coverage and emergency response plans to reassure the public.
