Border Patrol agent pleads guilty to starting 46,000-acre fire with exploding target

A Border Patrol agent pleaded guilty Friday to starting the Sawmill Fire that burned 46,000 acres southeast of Tucson, Arizona in 2017. Dennis Dickey was holding an off duty party to celebrate his wife’s pregnancy at which the gender of his baby was revealed. On April 23 he mixed colored powder into a Tannerite exploding target which would show blue or pink smoke when shot with a rifle, according to his attorney, Sean Chapman, as reported by the Arizona Daily Star. The target exploded as planned and started what became the Sawmill Fire. A witness recorded a video of the explosion.

A news release from the U.S. attorney’s office says Agent Dickey will make an initial payment of $100,000, then make monthly payments after that. According to the Arizona Daily Star and the Green Valley News, he agreed in court to pay $500 a month for the next 20 years, which adds up to $120,000, for a total of $220,000. He also will be sentenced to 5 years of probation and agreed to participate in a public service announcement with the U.S. Forest Service concerning the cause of the Sawmill fire.

The off-duty agent could not be charged with arson since it was not a willful act. He pleaded guilty to a misdemeanor charge of causing a fire without a permit, which may allow him to keep his job as a Border Patrol Agent.

Agent Dickey said he attempted to put out the fire but when that failed, he reported it. At one point during the next week at least 799 firefighters were working to put out the fire, which ran up costs of approximately $8.2 million according to the May 5, 2017 national Situation Report.

On April 23, 2017, the day the fire started, the Hopkins weather station not far from where the fire began near Madera Canyon, recorded a high temperature of 80 degrees, 11 mph WSW winds gusting to 25, and 6 percent relative humidity. The weather station is at 7,100 feet and the location of the party where the fire started is most likely around 4,000 feet. If correct, this would put the temperature at the fire origin between 90 and 100 degrees.

In court, Agent Dickey told the judge, “It was a complete accident”.

Exploding targets consist of two ingredients that when mixed by the end user explode when shot by a high-velocity projectile. They have caused many fires since they became more popular in recent years, have been banned in some areas, and caused the death of one person. In June, 2013 a man attending a bachelor-bachelorette party in Minnesota was killed after shrapnel from the device struck him in the abdomen. The Missoulian reported that several years ago a woman in Ohio had her hand nearly blown off while taking a cellphone video of a man firing at an exploding target placed in a refrigerator about 150 feet away. In Georgia in 2016 David Pressley’s leg was blown off by an exploding target that he placed in a lawn mower.

After the ingredients are combined, the compound is illegal to transport and is classified as an explosive by the Bureau of Alcohol, Tobacco, Firearms, and Explosives and is subject to the regulatory requirements in 27 CFR, Part 555.

Firefighters make progress on the Sawmill Fire in Arizona

Firefighters battling the 46,954-acre Sawmill Fire 23 miles southeast of Tucson have been able to slow the spread over the last two days in spite of strong winds. Satellite imagery from early Friday morning did not show any large concentrations of heat over the previous 24 hours. This does not mean the fire is out, and there is no doubt a lot of line building and mopup work still has to be accomplished.

For the last two days the Sawmill Fire has been most active on the northeast side where aircraft have been assisting firefighters on the ground to slow the spread.

A Red Flag Warning for strong winds is still in place for the fire area as well as most of southern Arizona and southwest New Mexico.

On Thursday the Arizona Department of Transportation reopened Arizona Highway 83 south of Interstate 10.

The Pima County Office of Emergency Management has lifted the pre-evacuation order for residents on the west side of Arizona Highway 83. Residents in the Hilton Ranch area remain under pre-evacuation notice. An evacuation order remains in place for Rain Valley.

Sources report shooter with exploding targets started the 40,000-acre Sawmill Fire

The Green Valley News is reporting that several sources they spoke with said a target shooter using exploding targets started what became the Sawmill Fire 8 miles east of Green Valley, Arizona. The shooter reportedly tried to put out the fire, but after he failed he called to report it. The officials in charge of suppressing the fire have not confirmed what caused it.

As of Thursday April 27 the fire has burned approximately 40,000 acres and required the evacuation of several areas. The Green Valley News reported that approximately $1.6 million had been spent to suppress the fire as of Wednesday afternoon.

(UPDATED at 9:10 a.m. MDT April 27, 2017)

The growth of the Sawmill Fire east of Green Valley, Arizona slowed Wednesday as decreasing winds allowed air tankers and helicopters to drop water and retardant to assist the firefighters on the ground. The only significant spread that we found on satellite images was an additional 400 acres on the northeast corner of the fire.

As of Wednesday night fire managers were still calling it 40,356 acres.

An evacuation order remains in place for Rain Valley. Since evacuation orders were lifted for Greaterville and Singing Valley, residents of those areas are being allowed through the Arizona Highway 83 closure to access their homes. Arizona Highway 83 remains closed to public traffic.

The area is under a Red Flag Warning on Thursday and Friday for relative humidities in the teens and strong winds. One of the priorities on Thursday is to use aircraft to help secure the firelines before the winds increase.

Today, April 27, a Type 1 Incident Management Team will assume command of the 606 personnel on the Sawmill Fire.

On Wednesday morning the incident management team called it 20,000 acres.

At 2:03 p.m. MDT on Wednesday a heat detecting satellite mapped growth of the fire on the south and northeast sides.

A fire that started Sunday morning, April 23 eight miles east of Green Valley, Arizona, has burned (we estimate) about 28,000 acres as of 2:38 a.m. MDT on Wednesday, April 26, 2017, and required evacuations for the communities of Greaterville, Singing Valley, and Rain Valley. It has spread to the east 21 miles, has a perimeter of approximately 63 miles, and crossed Arizona Highway 83 in multiple places.

On Tuesday the temperature in the fire area was in the low 70’s, the relative humidity was in the 30’s, and the wind was 12-18 gusting at 25-33 mph out of the west. The forecast for the fire area on Wednesday calls for conditions that could lead to significant additional fire spread toward the east and southeast, with temperatures in the mid-70’s, humidity dipping into the single digits, and winds out of the northwest at 10-20 mph gusting to 29.

Tuesday evening Jeff Andrews’ Type 2 Incident Management Team assumed command. Due to the increasing complexity, management will transition to a Type 1 Team on Thursday, April 27.

A full suppression strategy is being employed to protect nearby values at risk including homes, ranches and outbuildings, communications facilities, power lines, and the Arizona National Scenic Trail.
