FARMINGTON — A fire Thursday night engulfed a mobile home on Poplar Street in Farmington.

Shortly after 9 p.m., police received a call reporting a mobile home was on fire in the 700 block of Poplar Street.

Farmington police Lt. Darryl Noon said when the first officer arrived on scene, the officer reported the house was fully engulfed in flames.

He said no one was in the home at the time of the fire.

“There was a report that there was an explosion,” Noon said.

He said the explosion may have been from a small propane tank near the mobile home. 

The cause of the fire is under investigation, Noon said.

Last year, fires in the same southern Farmington neighborhood caused more than $120,000 in damage to private property. It took firefighters more than 100 hours to put out and investigate those blazes. In October, Raymond Montano was arrested in connection with those fires.

Noon said it was too early for him to comment on whether or not Thursday’s fire was connected to the fires last year.

Randy and Sherry Casena, who live in the area, stepped outside of their house on Thursday night to watch the blaze.

The two said they have watched all of the fires in the area because Sherry Casena is the manager of Barclay Rentals, which owns apartments in the area. When they hear about a fire near one of the rental company’s properties, they check on the property.

“We didn’t know that anything was going on until we heard the sirens,” Randy Casena said.

After they heard the sirens, the couple looked outside and saw the flames. At one point, they said they saw something explode.

“We’ve been seeing some ashes falling,” Sherry Casena said, picking up a piece of charred material that had fallen on the ground near her and her husband.
