MANLIUS TOWNSHIP, Mich. (AP) — State police say an explosion at a rural storage unit in western Michigan was probably linked to an appliance that enhanced the growth of medical marijuana.

Sgt. Scott Leroy tells The Holland Sentinel that the appliance generated carbon dioxide and was powered by propane. He says heat or a spark could have caused the explosion, which injured a man and killed a dog in an adjacent storage unit.
