Christopher Heinly, 26, is facing a slew of charges for his alleged role in the robbery of the AMC Marple 10 located on the 400 block of South State Road in Springfield.

The armed suspect entered the movie theater at about 11 p.m. on March 28th and took approximately $600 in cash before running out and getting into the passenger side of a getaway car.

According to police, a security guard at the theater followed the man into the parking lot and to the car when an argument ensued. The guard told police someone inside the car flashed a gun, so the guard fired a gun and hit the driver’s side door.

The suspects then drove away.
