Auburn self-storage business fire was arson

A fire department spokeswoman says investigators have determined that a four-alarm fire at an Auburn, Wash., self-storage business was arson.

Kimberly McDonald of Valley Regional Fire Authority says Wednesday evening's fire at Auburn Way Self Storage apparently began in a single storage unit in building "E".

Investigators are not discussing what was used to start the fire.

McDonald says fire investigators are following up leads in cooperation with Auburn police.

KOMO-TV reports that at least 14 storage units burned.
