Texas State Fire Marshals were the scene Monday of a weekend's fire to determine how the fire started, which included an office used by State Rep. Todd Hunter 

It was just after 4:30 a.m. Sunday morning when an unknown man knocked on the door of Fire Station 14 to tell the crew there about a nearby fire on the 5900 block of South Staples Street.

We are told that no one was inside the building at the time of the fire.

The Corpus Christi Fire Department was seen using a drone to get a bird's eye view of the damage.

The building, part of the Bay Area Professional Plaza, had major damage to the roof.
