A 15-year-old boy accused of fatally shooting his parents and three siblings in their wealthy Washington state home appeared in court Friday as investigators reveal chilling details about the killing spree.
The teenager has been charged with five counts of first-degree murder and one count of attempted murder in connection with Monday’s rampage in the unincorporated community of Fall City, roughly 25 miles east of Seattle. His parents, Mark and Sarah Humiston, along with three of his siblings – ages 7, 9 and 13 – were found dead when deputies arrived.
Prosecutors on Friday sought a hearing to determine whether the teen suspect should be tried in adult court. A plea will not be entered until the hearing, which is scheduled for June 4.
Authorities allege the teenager used his father’s gun that was stored in a lockbox. The suspected shooter was the only child in the home to know the code to the lockbox, according to court filings.
