DENVER (CBS4) – Investigators are trying to figure out what started an early morning fire in Denver.
Flames broke out shortly before 4 a.m. at a house at 40 Clarkson Street near 1st Avenue.
Officials said the fire started in the basement and they believe nobody was inside at the time.
Joules Poolski lives next door and woke up to the sound of shattering glass.
“When we came out here we saw flames coming out of the basement. There were about 2- to 3-foot flames just shooting out of the side of the house right there and so I immediately called 911 and yelled ‘Fire.’ My roommate went over and knocked on the door to see if anyone was there. No lights were on,” Poolski said.
A neighbor told firefighters they believed someone may have been making hash oil in the basement.
Nobody was hurt in the fire.
