A 42-year-old man accused of shooting seven people at a crowded nightclub south of Seattle has been charged with seven counts of first-degree assault.

King County prosecutors charged Cesar Chaparro-Vielma, of Covington, Wash., on Wednesday. He remains jailed with bail set at $1 million. Arraignment is scheduled Aug. 9.

Chaparro-Vielma is accused of shooting his estranged wife and her male friend as well as her two sisters. Three bystanders were also injured inside the Club Galaxy at the Muckleshoot Casino in Auburn, Wash. The facility is owned and operated by the Muckleshoot Indian Tribe.

According to court papers, the man told police he followed his estranged wife and her new boyfriend to the club and opened fire early Sunday because he "couldn't stand it."
