Suspect in slaying of rapper G Herbo’s friend facing weapons charge

Gun charges have been filed against a Lawndale man wanted in connection with the brazen South Loop barbershop slaying of rapper G Herbo’s friend, Chicago police said Wednesday.

Christopher Mosley, 29, was arrested Tuesday after being found with a gun during a traffic stop in the 1300 block of South Independence Boulevard after he was “identified as the offender wanted” in connection with the Jan. 28 shooting of Gregory Jackson III, police said.

As of Wednesday, police have not sought murder charges against Mosley, a spokeswoman for the Cook County state’s attorney’s office said.

When officers approached Mosley Tuesday, he was wearing a “knapsack” around the front of his body as he sat in the driver’s seat of the vehicle and the officers could see the butt of a Glock handgun with an attached laser sight poking out, prosecutors said.

The gun was unloaded but a loaded drum magazine was also found in the knapsack, prosecutors said.

The weapon was expected to be sent to the Illinois State Police Crime Lab to determine whether it was connected to Jackson’s murder, a source familiar with the case said.

Mosley, a convicted felon, is not allowed to possess a gun and an active 2019 court order notes that he is to be considered armed and dangerous if stopped by police, prosecutors said. That court order stemmed from a misdemeanor domestic battery case in which Mosley fired a gun at his girlfriend as she tried to get away from him after he struck her in the face while they were driving on Lake Shore Drive, prosecutors said.

Mosley has previous convictions for robbery, unlawful use of a weapon and residential burglary.

Prosecutors did not mention the homicide investigation in court.

“He is clearly a danger to the community,” an assistant state’s attorney said before Judge John F. Lyke Jr. ordered Mosley held without bail.

Mosley’s arrest was not captured by the arresting officers’ body-worn cameras and there was no indication he had committed any traffic offenses before the stop, an assistant public defender said.

Jackson — more widely known as “Lil Greg” — was in the Studio Nineteen barbershop, at 1931 S. State St., when a gunman walked in about noon and shot him in the face, according to police and the Cook County medical examiner’s office.

Jackson, 24, of South Shore, was pronounced dead at Stroger Hospital.

Earlier on the day he was killed, Cook County Judge Ursula Walowski sentenced Jackson to time served on a misdemeanor drug charge conviction, court records show. Jackson had pleaded guilty in exchange for the charge being reduced from a felony.

According to police sources, Jackson was a member of the South Shore-based No Limit Muskegon Boys gang — a renegade faction made up of members of both the Black P Stones and Gangster Disciples. “NLMB” is occasionally used as an acronym for the saying “Never Leave My Brothers,” as well.

G Herbo has long claimed an affiliation to NLMB, and in a 2012 song with fellow local rapper Lil Bibby, G Herbo said: “Yeah it’s no limit, thirty years runnin’, thirty years gunnin’ and we still the s---.”

Popular Atlanta rapper 21 Savage was among friends and fans who offered their condolences on social media after learning of Jackson’s killing.

Jackson’s mother, Nicole Griffin, said he was a father to two young children.

The last post on Jackson’s Instagram account features a smiling photo of him and G Herbo — whose birth name is Herbert Wright III — with a caption stating in part: “Can’t Nun Come Between Us.”

In a song released last year, G Herbo made an apparent reference to his close friendship with Jackson, saying: “Me and Greg was sharing clothes, but we wasn’t really bros.”

Last December, G Herbo and several members of his crew were charged in Massachusetts federal court for allegedly using stolen credit card details and IDs to pay for private jets, expensive meals and designer puppies over the last four years. G Herbo faces charges of wire fraud and aggravated identity theft.
