US teen charged with killing family tried to accuse brother, surviving sister says

Sister tells investigators Seattle boy, 15, accused of shooting parents and three siblings was in trouble for failing tests

A 15-year-old boy accused of killing his parents and three of his siblings this week east of Seattle tried to pin the deaths 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 on Thursday.

The boy was charged on 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.
