GREEN VALLEY (3TV/CBS 5) -- This gender-reveal party cost the State of Arizona over $8 million.
In September, off-duty Border Patrol Agent Dennis Dickey, pleaded guilty to starting the Sawmill Fire.
The fire started on April 23, 2017, near Green Valley, 25 miles south of Tucson.
The 37-year-old Border Patrol agent started the fire by shooting a rifle at a target filled with explosive powder.
In a new U.S. Forest Service video obtained by Arizona's Family, the target reads "boy" and "girl" on it. Once the shot is fired at the target, a blue powder appears and a brush fire starts moments after.
Dickey, who reported the fire immediately, agreed to pay restitution totaling close to $8.2 million. He also agreed to five years probation and to make a public service announcement with the U.S. Forest Service about the cause of the fire.
The Sawmill Fire burned nearly 47,000 acres in southern Arizona.
