Full Report
Details of the Incident
The fatal attack took place around 2:17 a.m. as the train traveled along the Blue Line. According to prosecutors, Pollion was asleep for approximately an hour and was not acquainted with Thurman. In a sudden act of violence, Thurman approached Pollion from behind, recording the assault as he stabbed him once in the chest and once in the abdomen with a knife featuring a bright-orange handle.
Witnesses reported that Pollion awoke screaming and attempted to escape before collapsing in the train aisle. He was transported to a nearby hospital but succumbed to his injuries shortly thereafter. After the stabbing, Thurman allegedly changed trains. Court documents indicate he later filmed himself making a remark about the incident.
Investigation and Arrest
Law enforcement quickly initiated an investigation, utilizing surveillance video from the train system that captured the attack and Thurman’s face. This footage was cross-referenced with Illinois’ facial recognition program, leading to his identification. A police officer who had encountered Thurman just days before recognized him due to previous interactions.
Thurman was apprehended the following Sunday, wearing the same outfit visible in the surveillance images. He was in possession of a cellphone with recordings related to the incident, alongside photos of other passengers on the train. A family member also identified him from the footage, and court documents suggest that Thurman admitted to the stabbing during questioning.
Context & Previous Events
Concerns about crime on public transportation have escalated in Chicago, particularly following a series of violent incidents. A notable case involved a man setting a woman on fire aboard a train last November. In response to rising crime rates, federal transit officials mandated that the agency develop a more stringent safety protocol, warning that failure to do so could result in significant financial penalties.
