Man Sets Wife on Fire at Gas Station [VIDEO]

I'm still trying to wrap my head around this whole ordeal involving a husband and wife at a gas station in Atlanta, Georgia. While pumping gas this guy pulls out a lighter (not sure if he was actually lighting a smoke) and lights it up causing gas fumes to ignite. Then the man pulls out the gas nozzle and throws it, this caused the man's wife to go up in flames. It's hard to tell if this was an accident or if it was intentional. There is now a warrant out for the husband's arrest.
