BOULEVARD PARK, WASHINGTON — A customer at a 7-11 shot and killed a masked man wielding a hatchet after he attacked the clerk Sunday morning. <br /> <br />The attack occurred in the area of S 112th St. & 8th Ave S. in the Boulevard Park area of Burien. <br /> <br />King County Sheriff Sgt. Cindi West told KING 5 News that a man came into the store with a hatchet, attacking customers and a clerk before another customer shot and killed the suspect. <br /> <br />Kuldeep Singh, the clerk at the store, received a gash on his stomach but is alright. <br /> <br />The customer, a 60-year-old Seattle man, was not injured. West said the case will be forwarded to the prosecutor’s office for evaluation but the initial stages of the investigation show no wrongdoing. <br /> <br />The 60-year-old is a regular customer and a licensed concealed gun carrier, according to the sheriff’s office. <br /> <br />“There’s a chair that sits really close to the clerk’s counter. He was sitting back there having his morning coffee,” West said. “The guy came in with a mask just swinging the hatchet at both of them.” <br /> <br />That’s when the customer took out his pistol and shot the suspect. <br /> <br />The suspect, believed to be in his 40s, has not yet been identified. Medics at the scene were not able to revive him.
