Escambia County Fire Rescue says there have been an unusually high number of fires on Pensacola Beach this year. Escambia County Interim Fire Chief Paul Williams said firefighters usually respond to one or two structure fires a year on Pensacola Beach, but this week alone, firefighters responded to three structure fires within four days, one of which destroyed a vacant rental home in the 900 block of Panferio Drive. Causes of all three fire remain under investigation by the Florida State Fire Marshal’s Office. Williams said he did not believe the fires were connected.
