Early Wednesday morning, Kirkland police investigators made three arrests associated with a homicide that occurred on the evening of September 16, 2020 at Houghton Beach Park.

Joshua S. Hawthorne, Chrisean J. Kaufman and Calvin S. Vao, all under 20-years-old, were all charged with first degree murder by King County prosecutors in relation to the killing of 18-year-old Cyrus S. Mason.

Police found Mason bleeding of multiple gunshot wounds at the public swim dock at Houghton Beach Park on the night of the crime. Later, he was pronounced dead at Harborview Medical Center.

Police reports say the suspects stole a AM-15 rifle from the victim after killing him. It is believed the victim was meeting the suspects for an apparent trade or sale of the weapon.

The suspects arraignments, where they are expected to enter a plea, are scheduled for March 3rd at the King County Courthouse.
