PALM BAY, Fla. (AP) — Investigators searched Tuesday for one or more arsonists behind a string of stubborn wildfires that have destroyed or damaged more than 160 homes on Florida's Atlantic coast.

Firefighters in Brevard County were trying for the third day to contain fires that have scorched an estimated 10,000 acres, or more than 15 square miles, in and around the neighboring towns of Palm Bay and Malabar.
