LAFAYETTE, Colo. — One person died in a house fire Wednesday morning, the Lafayette Fire Department said.

The first-alarm fire happened in the 800 block of Dounce Street just before 10 a.m.

Rocky Mountain Fire responded first, followed by the Mountain View, Louisville and Lafayette fire departments.

Lafayette Fire Chief Dave Friedel said firefighters had a difficult time moving through the home because of the contents.

It took crews about 15 minutes to get the fire under control.

While the fire is not believed to be suspicious, an investigation is underway with the Lafayette Police Department leading the effort.

Lafayette Fire Cmdr. Brian Rosipajla said the victim was the only person inside the home. Construction workers next door called about the fire.

The victim has not been identified.
