SEATTLE (AP) – Authorities say two people were found dead in a fire that burned a home housing a marijuana grow in Seattle.

Hilton Almond with the Seattle Fire Department told KOMO a witness called 911 to report the fire around 5:45 a.m. Monday.

Firefighters arrived to find huge flames on the south end of the home. Once firefighters made it inside, they found two bodies, but no additional information on the victims was available.

Almond says the cause of the fire is under investigation and it’s unclear at this point whether it was related to the marijuana grow.
