DENVER - Three men have been charged with arson after allegedly triggering an explosion and fire Sunday while making hash oil with butane gas.
Jeff Garbarek, 39, Steve Donnel, 39, and Scott Mitchell, 43, are each charged with one count of felony arson, said Lynn Kimbrough, spokeswoman for the Denver District Attorney's Office.
The men are accused of using butane fuel to make hash oil, a high potency extract of marijuana, in a Julian Street home in Denver, said Mark Watson, spokesman for the Denver Fire Department.
When the concoction exploded, one person suffered minor burns and was treated on scene, Watson said. Damage to the duplex was not significant, but windows were blown out.
The charges allege the men triggered the fiery blast, placing the owner of the next-door duplex at risk of serious injury.
Several explosions in Colorado and around the country have been caused by people trying to make hash oil with butane. Denver's fire department began tracking such marijuana-related fires on Jan. 1, when recreational sales of the drug became legal in Colorado.
Garbarek, Donnel and Mitchell are due in court on April 9 to be formally advised of the charges against them.
