SEATTLE—A 15-year-old boy accused of killing his parents and three of his siblings this week east of Seattle tried to pin the slayings on his younger brother, but a sister who survived after playing dead escaped to a neighbor’s house and told police who really carried out the shootings, authorities said in a court document made public Thursday.
The boy was charged Thursday in juvenile court with five counts of aggravated murder. Under Washington state law, a hearing is required before the case can be moved into adult court.
