THORNTON, Colo. — One person was injured after a house and a van caught fire in Thornton on Wednesday morning, sending a large plume of smoke into the sky that was visible for several miles across the metro area.

The fire broke out before 7:30 a.m. in the 9200 block of Yucca Way, the Thornton Fire Department said.

Investigators are working to determine if the fire started in a carport and spread to the house or vice-versa.

One person was inside the home and got out, but was taken to a hospital to be treated for smoke inhalation.

The fire was so large at one point that firefighters had to stay back, a fire spokesman said.

The house suffered extensive damage and likely will be declared a total loss. The van was completely destroyed. A next-door home suffered some heat damage from the flames.

Firefighters from Federal Heights and Adams County responded to assist the Thornton Fire Department in battling the fire.

The cause of the fire is under investigation, but it’s not being deemed as suspicious, the fire spokesman said.

The Red Cross said three adults and two children were displaced from the fire.
