The video also shows someone else get out of the truck before creeping up to the front door of the convenience store and opening fire, FOX 4 News reports. Three teenagers were killed and a fourth was wounded in the shooting.

A 14-year-old was previously arrested because police initially believed he was the gunman. Detectives recently learned that he has intimate knowledge of the shooting, and he has been cooperating with the investigation. Based on the new information, the teen is not being charged at this time and has been released to his family.

The shooting appears to be a retaliation from a previous disturbance and law enforcement officials believe the incident to be a targeted attack on one or more of the persons inside the store.
