CARR, Colo. - Sheriff's officials say a house explosion that injured three people in Carr may have been caused by production of a marijuana concentrate like hash oil or marijuana wax.
Authorities say two men were taken to a hospital with severe burns on their hands and arms after the explosion Aug. 11, and a 7-year-old boy had minor injuries. The boy initially was identified as age 4.
Weld County sheriff's officials said Wednesday that the two men are still being treated for the burns.
Deputies who searched the house found evidence that marijuana was being grown there, and the residence had a medical-marijuana permit posted. Sheriff's officials say preliminary findings are that some form of process for producing concentrated marijuana may have caused the explosion.
No criminal charges have been filed yet.
