Fire officials are investigating the cause of an overnight blaze in northwest Denver that destroyed a discount store.
No one was hurt in the fire at the Dollar City store, but it took 65 firefighters more than an hour to put out the fire. The building's roof collapsed, but a Denver Fire spokesperson says all firefighters got out without injury.
The fire comes a few months after another discount store across the street was also destroyed in a fire. Officials say they've made no connection between the two fires.
