LONGMONT - Longmont police say a marijuana extraction process to produce hash oil may have been the cause of a garage explosion in Longmont Wednesday.
Police say two people were injured. Three others are facing arson charges.
The small explosion and fire occurred around noon at a house near South Pratt Parkway and Missouri Avenue in Longmont.
In August, two people were injured, including a 7-year-old boy, following a Weld County home explosion blamed on the same marijuana process.
