INITIAL REPORT: The Yellowstone County Sheriff's Office, with help from Lockwood fire officials, is investigating a fire that started in mobile home on Thursday morning.
While firefighters were able to douse the fire at 206 Hemlock Drive within a few minutes of arriving at about 4:15 a.m., investigators from Lockwood Fire and Rescue and the sheriff's office remained at the home hours later.
Lockwood Fire Chief Bill Rash said the fire was reported at 4:11 a.m. and two engines arrived seven minutes later. Smoke and flames were coming from the building's north side, which appears to be the kitchen area.
Fire crews managed to get inside the home and had the flames under control within 10 minutes, Rash said.
"They went in and were able to stage an interior offensive," he said.
Rash said the fire caused serious damage to the interior of the home. Details of its occupants and any possible injuries were not known.
"The structure sustained extensive damage and there were no firefighter injuries," he said in an 8:20 a.m. news release. "At the time of this press release, the identities of the tenants/owner or insurance information was not available."
Rash said the early investigation didn't reveal anything suspicious but that it's still very early in the process. He referred further questions to Yellowstone County Sheriff Mike Linder.
Linder could not be reached immediately for comment.
Before fire crews arrived, a pair of neighbors tried to get into the home to see if anybody was inside.
Troy Donges lives across the street and said that a man, possibly in his early 30s, lives in the house and that he thinks a woman and several children had moved out earlier this month.
Donges' son was up listening to music when he heard a loud bang and thought an animal had hit the side of their home. He looked out the window, saw flames and woke up his dad.
"When I saw the flames, I ran outside," he said. "There used to be a family that lived there and that was my first thought."
He wasn't sure how hot it was inside and started banging on the side of the trailer, both to test the heat and to wake up anybody who might be inside.
"I was hitting the trailer as hard as I could with my hand," Donges said. "There was so much smoke in there, I don't know how anybody could've survived. People told me every time I hit it, it sounded like a gunshot and it woke them up."
Dale Holthues lives next to the mobile home that caught fire and said he was in bed when a motion light in the driveway went off, catching his and wife's attention.
He said that once they saw the flames, he ran to the home to try to get occupants out while his wife called 911.
Holthues tried to kick in two different doors, while Donges banged on the house's sides, but couldn't get them open and received no response from inside.
"We could not get any results," he said. "I don't if they were sleeping or what."
Neither man knew for sure if anybody was inside or anybody was injured. An empty Lockwood ambulance could be seen leaving the area at about 6 a.m.
The investigation is ongoing. Sheriff's deputies were searching vehicles parked in front of the home. Yellow crime scene tape was placed around the driveway to the home and part of Hemlock Drive was closed to traffic.
Lockwood fire responded with 17 firefighters, two engines, a ladder truck, an ambulance and a command vehicle. NorthWestern Energy also responded.
