CHICAGO — A slain Streets & Sanitation worker was on his way to a birthday party Saturday when he was gunned down in Back of the Yards, relatives said. There’s now a $7,000 reward for information leading to an arrest.

“He never did anything to anybody to deserve that,” Ernest Leggs said of his older brother, 32-year-old Terrell Jones.

Jones was gunned down in Back of the Yards about 10:30 p.m. Saturday near 50th Street and Ashland Avenue when two people exited a dark SUV and began shooting, according to authorities. Jones’ cousin, a city transportation worker, was grazed in his hand.

Leggs is a senior airman in the U.S. Air Force who was set to be deployed Monday. He instead remained in Chicago to plan a funeral and mourn his brother.

“There’s no reason that any of us should be standing in this spot right now because it was senseless,” Leggs said. “He wasn’t a gangbanger. He wasn’t a thug. He was a working man. He worked everyday. He took care of his kids. That was his priority.”

Jones and his wife, high school sweetheart Shenae Jones, had three children: a 9-year-old boy and 3-year-old twins.

“It’s been unmanageable,” Shenae Jones said. “I’m not even comprehending it. … Just taking it one day at a time, trying to cope with what happened. It’s a process that I’m not ready for. I can’t.”

Investigators previously said they believe the attack could’ve been the result of road rage.

A $7,000 reward is being offered for information about Jones’ murder that leads to an arrest, WGN’s Sean Lewis reports. There’s an anonymous tip line at 1-800-883-5587.

A second city worker with Streets & Sanitation, Darnell Simmons, was exiting a store on Central Avenue near Fulton Street in Austin when he was shot and killed about 6:30 p.m. Sunday.

Chicago Police Supt. Eddie Johnson on Monday called both cases “open and active,” noting that detectives are currently combing through video and ballistic evidence. Johnson offered “heartfelt condolences” to both victims’ families.
