SEATTLE (AP) — Police in Seattle and Shelton, Wash., report that two residential explosions are believed to have been caused by a marijuana extraction process. Four young people were injured in the Shelton blast.
KING-TV reports that Shelton authorities say three 20-year-olds and one 17-year-old were manufacturing hash oil Tuesday afternoon at a home when it was hit by a powerful blast.
Neighbors say the blast knocked a wall off the foundation.
KING reports the four drove themselves to Mason General Hospital. Three were transported to Harborview Medical Center in Seattle with burns. The fourth person was treated and released.
Seattle police were suspicious when a man said a blast Monday night at a Lake City residence was caused by a refrigerator explosion.
Investigators determined the blast actually was the result of a marijuana extraction process. The explosion broke four windows and moved the back wall of the house 3 inches. There were no injuries.
