Cop accidentally kills security guard at bar in Chicago suburbs: report

A police officer mistakenly shot and killed a security guard at a bar in Chicago's south suburbs early Sunday morning, Chicago’s Fox 32 reported.

Witnesses said a security guard told a group of "drunk men" to leave a Robbins bar around 4 a.m. An armed suspect later came back inside the bar and opened fire, WGN-TV reported, citing witnesses.

Armed security guards returned fire, the report said. One the guards -- Jemel Roberson, 26 -- apprehended the suspect outside, witnesses said. Roberson then requested help from Midlothian Police, the Cook County Sheriff's Office said.

I guess when the police got there, they probably thought he was one of the bad guys, cause he had his gun on the guy and they shot him.

A witness told the station that Roberson was holding the suspect on the ground when one of two responding officers fatally shot him.

"The security guard that got killed, he caught somebody and had his knee on him the whole time," said one witness cited by Fox 32. "Just waiting on the police to get there. I guess when the police got there, they probably thought he was one of the bad guys, cause he had his gun on the guy and they shot him."

CHICAGO OFFICER CONVICTED IN SHOOTING RETURNS TO COURT

Four other people, including the shooter, suffered non-life threatening injuries, WGN-TV reported. Midlothian police confirmed that one of its two responding officers opened fire. The officer's identity was not released.

Roberson was reportedly a church organist who was training to become a police officer.

"He was getting ready to train and do all that stuff,  so the very people he wanted to be family with took his life," said Pastor Patricia Hill of Purposed Church.

The Cook County Sheriff's Office is investigating the first shooting, while the State Police Public Integrity Task Force is investigating the police shooting.

Robbins is a sparsely-populated village about a 30-minute drive south of Chicago.
