Oak Park police have charged a Chicago man with four felony counts related to the armed robbery Sunday of a convenience store.

Jerrod E. Hall, 23, of the 5500 block of W. Bloomingdale, is charged with four felony counts, including armed robbery, aggravated possession of a stolen motor vehicle, aggravated unlawful use of a weapon and aggravated fleeing and eluding. He has an initial court appearance Friday at the Maybrook courthouse.

The robbery occurred around 10 p.m. Sunday at the 7-Eleven store at 661 South Blvd., on the corner of South Boulevard and Euclid. A witness said he was entering the store at the time a man described as Hall was walking out. The clerk behind the counter looked very shaken, the witness said.

“Her eyes were as big as saucers,” the man said. “The lady said, ‘I’ve just been robbed.'” The witness said she told him the robber stuck a gun in her face and took cash from both store registers.

Police were called, and got a description of the man and the car, which was radioed to patrol squads.

An officer soon spotted Hall driving an Oldsmobile Bravada near Washington Boulevard and Ridgeland Avenue and followed him. He attempted to pull Hall over at Washington and Lockwood in Chicago, but Hall fled.

Shortly after Hall reportedly abandoned the car in an alley behind the 5400 block of Adams, Chicago police spotted and arrested him on a rear porch on the 5400 block of Ohio. A .45 caliber handgun was recovered in the alley behind a building on the 5400 block of Race.

The robbery victim and the other witnesses were then taken to the Chicago location, where they identified Hall in what’s called a street show-up.

Jorgensen called the process of tracking down and apprehending Hall “great old-fashioned police work.”

“The officer who initiated (the pursuit) did it on a pure gut reaction after seeing a car matching the description,” Jorgensen said.

He also praised the high level of cooperation between Oak Park and Chicago police in setting up a perimeter in the Austin neighborhood. Aside from the darkness and being in an unfamiliar neighborhood, Oak Park officers had to contend with a hidden suspect reported to have displayed a silver handgun.

“I think they did an excellent job,” said Jorgensen.
