The U.S. Forest Service has released video footage of the moment an off-duty Border Patrol agent started Arizona’s April 2017 Sawmill Fire by shooting at an explosive target. Agent Dennis Dickey was taking part in a gender reveal party for his baby when he shot at the box-like target, which read “BOY GIRL” and was rigged to release colored smoke indicating the child’s gender. In the video, which was taken by a party attendee and later released to The Arizona Daily Star, the sound of a gunshot is heard before the target explodes.
