A firefighter with the Southern Dallas County Fire Department has been charged by prosecutors with setting fire to a house, then taking a tanker truck to fight the flames.
Daniel Truster is charged with second degree arson.
Investigators say a man who was with Truster on Christmas Eve told them the firefighter mixed gas and degreaser in a bottle and used it to light the fire.
The fire damaged a home in Elkland.
Authorities say Truster called 911 to report the fire, then fought the fire.
No one was hurt.
Truster has been suspended from the department.
