A lamp that was being used to grow six marijuana plants is possibly to blame for that fire in Yonkers last week that killed one resident of an apartment complex and injured 41 others, including 14 firefighters. Published reports said the blaze started on the first floor of the building on Bronx River Road. Investigators reportedly believe the lamp fell, and set the floor on fire. The fire is under investigation by the Westchester County D-A’s Office.
