A hatchet-wielding man was shot and killed after storming a Burien, Washington 7-Eleven on Sunday.
The shooter was a 60-year-old regular customer who saw the attacker slice the store clerk's stomach, the King County Sheriff's Office said according to the Seattle Times .
The masked man attacked the store clerk without a word before the customer pulled out a handgun and shot the assailant, the newspaper reported.
Western Washington-based KIRO 7 News reported the clerk said he would have been killed had it not been for the customer, whose identity was not released. The clerk called the customer a "very nice" guy, according to the station.
