Police were searching for a gunman who killed three women and injured two other people at a Washington state mall before fleeing the area. A gunman opened fire in a crowded mall north of Seattle. The Washington State Patrol said the four were shot on Friday at the Cascade Mall in Burlington, about 105km north of Seattle. It previously said four people had been killed. "We have one adult male victim from the Burlington mall shooting who arrived by air this evening to Harborview Medical Center at approximately 9:30 p.m. He is in critical condition," said hospital spokeswoman said. “We are still actively looking for the shooter. Stay indoors, stay secure,” authorities said. Authorities released a surveillance image of a suspect apparently walking through a store and holding a rifle. They described the suspect as a Hispanic man wearing black who was last seen walking toward Interstate 5. The Cascade Mall is an enclosed shopping mall in Burlington, Wash., that opened in 1990, according to the mall’s website. It features J.C. Penney, TJ Maxx, and Macy’s stores, among other shops, restaurants and a movie theatre. Cascade Mall is a popular destination for shoppers from British Columbia.
