Occupants of the apartment where the fire started had a mattress on the balcony Monday night, and had the balcony enclosed in blankets, South Davis Metro Fire Agency Chief Jeff Bassett said.
Around midnight, they were on the balcony smoking and discarded their cigarettes into a bottle on the mattress and went to bed. Embers from the cigarette started the blaze, Basset said.
About 20 people were displaced and 12 units damaged in the blaze. A Davis County Sheriff’s deputy first saw the fire and started evacuating residents.
