CARR, Colo. - Three people, including a 7-year-old boy, were injured in a house explosion and fire in Carr, Colo., earlier this month.
Clayton Smith, 30; Levi Allen, 28; and the 7-year-old boy were treated for injuries. The two men had severe burns and the boy had minor injuries in the Aug. 11 incident at 61673 Fourth St.
According to a news release issued Wednesday, a search warrant was executed at the Carr residence and deputies found evidence of marijuana being grown at the residence along with a posted medical marijuana permit at the residence.
"Preliminary findings of the investigation indicate that some form of extraction process to produce a marijuana concentrate from the marijuana plants -- known as 'Hash oil' or possibly 'marijuana wax' -- may have been the cause of the explosion inside the residence," the release from the Weld County Sheriff's Office stated.
No formal charges have been filed on both persons of interest as of Wednesday and their photos were not released.
Sheriff John B. Cooke said the investigation of the incident is ongoing.
Carr is located in northeast Weld County, near the Wyoming border, between Interstate 25 and Highway 85.
