Border Patrol Agent Dennis Dickey, who has admitted starting the fire with an explosive target, ignited the blaze during a gender reveal party that was held to show the gender of his wife’s expected baby, his attorney Sean Chapman told the Star in September. Since gender reveal parties typically use blue smoke to announce a male baby and pink smoke to announce a girl, Dickey’s wife presumably was expecting a boy.

Dickey agreed to pay $220,000 in restitution after he pleaded guilty Sept. 27 in federal court to a misdemeanor charge of causing a fire without a permit.

The wildfire began when Dickey shot a target that contained Tannerite, an explosive substance designed to detonate when shot by a high-velocity firearm, U.S. Forest Service Special Agent Brent Robinson wrote in an affidavit filed Sept. 20 in U.S. District Court. The explosion was caught on film by a witness.
