 The video shows men in Halloween masks robbing a Citgo, where the gas station clerk was shot.

 In the video the men enter the store with a gun raised, grabbing items and running away.

 The shooting happened in January of last year. The clerk, Saeed Sharwani, was counting money to close up for the evening.

 Police say they later narrowed the suspect down to Malone and he matched the description.
