Surveillance footage shows a man and a woman enter the store. The man places a doorstop, continues walking in and then pulls out a gun.
In the video, the man continues walking through the store, as he points the gun at the store owner.
He then goes behind the counter searching for money.
An employee tells ABC13 the suspect placed the doorstop because he knew they could lock the doors. The suspect reportedly also knew where the money was kept.
