Screams. That is how Joyce Mobley learned of her son Julian Mobley’s stabbing death.It happened while he was working as a janitor at the Near West Side’s Damen Avenue Green Line station — coming to the aid of another staffer who’d gotten pepper-sprayed. Joyce Mobley's daughter was in another room and had taken a call from Julian’s wife. “I could hear my daughter in the front bedroom screaming," Joyce Mobley said. “That’s how I got the news.”Hardly able to hold on to the steering wheel, Joyce Mobley drove to Stroger Hospital to see her 41-year-old son.“It’s terrible," she said, adding that the only solace she has found is the thought of him resting after enduring such pain during the attack that reportedly occurred at 3 p.m. at the Damen Green Line station, 154 N. Damen Ave. “It helps my heart. I know he’s at peace because he’s asleep. Now he’s OK,” she said.The attack unfolded as the suspect, who is now in police custody after turning himself in, began to fight with another CTA worker, possibly a conductor, said Julian's mom. Julian, who witnessed the fight, had turned his back to help the staffer, who couldn’t see after having been pepper-sprayed by the suspect. That's when the suspect, brandishing what appeared to be scissors, stabbed Julian in the back of his neck, according to a police report obtained by the Chicago Sun-Times. Julian then "ran around the courtyard of the station and went inside of his utility room," where firefighters and paramedics from Ambulance 53 found him, the report said. He was taken to Stroger Hospital in "very critical condition," but he was pronounced dead a short time later. A Friday autopsy determined he died of a stab wound to his neck, and his death was ruled a homicide, according to the Cook County medical examiner's office. “It was a natural reaction. He was trying to help his co-worker clear his eyes," said Joyce Mobley, who was told that her son was trying to render aid before being stabbed. “He turned his back on the perpetrator. He didn’t think the perpetrator was upset with him,” his mom said. “That’s inhumane." Dwayne Mobley is the father of Julian Mobley, a CTA janitor fatally stabbed Thursday afternoon while working at the Green Line station on the Near West Side.Anthony Vazquez/Sun-Times Julian grew up in Woodlawn, where he lived with his wife and two kids. They had a close-knit family, with many aunts and uncles and a small circle of good friends. He was one of four Mobley siblings — three boys and a girl, said his mom, who added the siblings are all adults now.He attended Hyde Park Academy High School at 6220 S. Stony Island Ave. until being forced to leave because of bullying, his mom said. Julian was 14 years older than one of his brothers, and he took pride in being a big brother.“He was kinda bossy,” his mother joked.Lately, he had only wanted to spend more time with his family and his brother, whom he'd started working out with at L.A. Fitness after shifts at the CTA. He’d worked at CTA since 2018. “He was hardworking, and he was a kind man,” his mom said. “A friendly man.”Julian changed his diet and started taking vitamins, his mom recalled. “He came to understand he had to eat a certain way to gain weight,” his mom said.His family had been looking forward to another trip to Disney World in Orlando, Florida, and Julian was saving money for it. Earlier, he had taken his 14-year-old daughter, but this time he wanted to go as a family, including their new baby and 1-year-old boy. “They were saving money for the future," she said.Stricken with grief, Joyce Mobley is also disturbed by the feelings of worry.“It just makes me worry about everyone’s life because it could have happened to any one of us." In a statement, the transit agency offered condolences:“We will support law enforcement officials’ efforts to ensure that the offender is apprehended and prosecuted to the fullest extent of the law.”Julian was mild-mannered and kind, and his eyes lit up when he talked about his children, according to rail janitor and Local 308 union board member Audrey Veasley.“He was a gentleman,” Veasley said during a news conference hours after the incident. “He was a real man.”No charges have been announced. ...read more read less
