NAPLES, Fla. - Firefighters in East Naples battle a fourth suspicious fire in one neighborhood.

In less than three weeks, three other fires within a mile of Painted Leaf Lane have been called suspicious.

Multiple agencies, and nearly 50 crew members worked on the blaze that engulfed a two story house.

Like the other fires, crews say this house was also vacant. The Fire Marshal has been called out to investigate.
