JACKSONVILLE, Fla. -- A good Samaritan contributes to the arrest of an alleged armed robber.
The Jacksonville Sheriff's Office arrested Steven Mark Riley for an alleged armed robbery that took place Sunday at the Publix on Atlantic Boulevard.
According to police, Riley pulled up behind a woman in the parking lot and took her purse from her cart as she loaded groceries into her car.
They say she tried to stop him, but he threatened her with a gun.
When the suspect tried to get away witness Simeon Tyler said he snapped pictures with the phone on his camera.
Yesterday, during an unrelated traffic stop, JSO said officers were able to match the suspect's vehicle with the pictures from Tyler.
