Filmed on April 23, 2017, the clip shows an impromptu lens with the words "Boy" and "Girl" written on it, located in the middle of the desert near Green Valley, Arizona, south of Tucson.
Seconds later we hear a shot, and the target explodes, revealing a blue cloud and immediately igniting the surrounding brush. Someone shouts: "Start packing!"
The expectant father, 37, had packed the target with a highly explosive substance called Tannerite and shot him with a high-powered rifle, according to the US Attorney's Office. UU The target was supposed to explode in pink or blue to reveal to the attendees whether Dickey and his wife were expecting a boy or a girl.
CNN has contacted Sean Chapman, Dickey's lawyer, but has not received a response.
As part of his plea agreement, Dickey will make a public service announcement with the Forest Service about the cause of the wildfire.
According to KGUN, the Dickey have not said whether the child was a boy or a girl. But the blue puffs when the target exploded could be a clue.
