University of Illinois at Chicago officials issued a warning Tuesday about a food worker who is at large after shooting two people in a Chicago home Monday.

Officials said an contracted Aramark employee, identified as Glenn Rhymes, who works at UI Health got into an argument with a patient Monday morning. During that argument, UIC officials say Rhymes pulled out and brandished a gun, and made a threatening statement.

Rhymes was taken into custody by UIC police and the gun was taken from him. UIC officials said the gun was not fired, and no one at UI Health was injured.

UIC police released Rhymes from custody a short time later. They listed the incident in their crime log, noting he was charged with having a firearm in a prohibited location. It’s not clear how Rhymes was released or why.

UIC officials said later in the day, they learned that Rhymes allegedly shot two people in their home, one of whom was another Aramark employee who worked at UI Health.

UIC said Chicago police are leading the investigation into that shooting. CBS News Chicago has reached out to CPD for more information but have not yet heard back.

Aramark released a statement saying they are cooperating fully with authorities and said “the person involved is no longer with our organization.”

Tuesday UIC public safety officials alerted the campus to police activity at 1801 West Taylor Street. Officials said the activity was precautionary but related to the incident Monday.

CBS News Chicago has reached out to the Cook County State’s Attorney’s Office to see if they approved any charges and learn why the suspect wasn’t required to report to court Tuesday. We are still waiting to hear back.

If you see Rhymes or have an information about his whereabouts, UIC officials are asking you contact university police at 312-355-5555 or contact Chicago police by calling 911.
