Investigators said witness statements and evidence collected at the scene have led them to believe the fire was a result of an argument between a man and woman that led the woman to fire a flare from a pellet gun that missed its target and set vegetation ablaze behind Belvoir Springs in the 36900 block of Mission Boulevard.
