A family argument over the care of an elderly loved one turned deadly on a Sunday night in Chicago, ending the life of 54-year-old Mark Hurn. The fatal shooting took place on September 27, 2026, in the Greater Grand Crossing neighborhood on the city’s South Side.
The dispute occurred at a residence in the 500 block of East 76th Street. According to police reports, a heated argument began inside the home concerning the care of an elderly mother.
The argument involved Hurn, his girlfriend, and his girlfriend’s brother. A witness later told investigators that during the quarrel, the brother became increasingly hostile toward Hurn. The confrontation escalated when the brother asked Hurn to “step outside.”
Shortly after the two men went outside, relatives still inside the house heard the sound of three distinct gunshots ring out in the night air, at approximately 10:40 p.m. When they rushed out, they discovered Hurn had been shot. The man who had argued with him, his girlfriend's brother, was seen running away from the scene on foot.
Police and paramedics were dispatched to the address following a call for a person shot. They arrived to find Mark Hurn suffering from multiple gunshot wounds to his chest, abdomen, and legs. He was immediately transported to the University of Chicago Medical Center, a Level 1 adult trauma center that has served the South Side since 2018. Despite the efforts of the medical staff, Hurn succumbed to his injuries and was pronounced dead at 11:22 p.m., just over 40 minutes after he was shot.
The Chicago Police Department assigned the case to its Area 2 detectives, who launched a homicide investigation. The suspect was identified by witnesses as Hurn’s girlfriend’s brother, but he had fled before police arrived. As of late September 2026, no arrests had been made in the case, and the investigation remained active. It was not publicly known if the weapon used in the shooting was legally owned.
The shooting occurred within the 3rd District, also known as Grand Crossing, a police district that patrols Greater Grand Crossing, Woodlawn, and South Shore. The Greater Grand Crossing community area has historically struggled with a high per-capita homicide rate compared to other parts of the city. While Chicago had experienced a significant drop in its overall homicide count in 2025, homicides related to domestic violence had risen by 15% that same year, a trend that prompted the Cook County State's Attorney to create a specialized unit to handle such cases in March 2026.
No public vigils or fundraisers for Mark Hurn’s family were immediately announced following his death. The investigation into his killing is ongoing.
