One of the three missing people from Colorado’s Marshall Fire has been found, according to Boulder County Sheriff Joe Pelle at a press conference on Sunday.

On Thursday, the Marshall Fire ripped through Boulder County, leveling subdivisions and charring over 6,000 acres. The found missing person was from Superior, which is about 24 miles northwest of Denver.

“We are still looking for a woman from Superior and a man from the area around Marshall. The search for those individuals is still ongoing,” Pelle stated on Sunday.

According to officials, there have been no reported deaths as a result of this fire.

The cause of the fire is still being investigated, but a search warrant was executed on a private property, according to Pelle. He also stated that they are aware of a viral video of a shed on fire in the area where the wildfire started.

“We don’t know if that shed or anything around it started the fire or if it was a secondary cause,” Pelle said.

Pelle acknowledged that authorities had spoken with residents about the fire.

“We’ve spoken with people, and I’m not going to get into the investigation,” Pelle said.

According to Louisville Police Chief David Hayes, a man was arrested Thursday afternoon for threatening firefighters who were working during the Boulder County wildfire.

“A man armed with an assault rifle had threatened the firefighters working in the area,” Hayes explained. “A number of officers responded – both Louisville officers, Boulder sheriff’s deputies, and I’m sure others – and we were able to safely arrest that person.”

According to the chief, they recovered “a couple of weapons.”

Hayes was unable to explain why the man was threatening the firefighters. He also couldn’t say whether the man lived in the neighborhood.

When asked if the man was attempting to protect his property, the chief stated, “I think (he) was probably just angry and upset like a lot of people are, but that’s obviously not the way to do it.”

The Marshall Fire was one of two that erupted early Thursday morning. Its flames sped across drought-stricken land, traveling “down a football field in a matter of seconds,” Gov. Jared Polis said at a news conference on Thursday.

The other fire, known as the Middle Fork Fire, was quickly attacked and “laid down,” according to Pelle.

The Marshall Fire impacted areas have since received about 8 inches of snow, dousing the flames but leaving many homeless and cold. In Boulder County, the fire has destroyed nearly 1,000 homes.

According to FEMA administrator Deanne Criswell, approximately 100 FEMA personnel have been assigned to assist victims of the Marshall Fire. Criswell, who surveyed fire damage with Polis before speaking to reporters on Sunday morning, said FEMA representatives will be at the disaster assistance center “starting today” to register people seeking extra help for expenses not covered by homeowner’s insurance.

Last week, President Joe Biden issued an emergency disaster declaration, and on Saturday, he issued a major disaster declaration. According to the major disaster declaration announcement, federal funding is now available to Boulder County residents, including grants for temporary housing and home repairs, as well as low-interest loans to cover uninsured losses.

A number of residents in the burn zone are still without power. “Within the burn zone we have roughly a thousand customers that remain without power,” said Alice Jackson, president at power company Xcel Energy-Colorado.

The process of restoration is ongoing, she said.
