The plane was taken by a 29-year-old Sumner man about 8 p.m. and crashed on Ketron Island, near Steilacoom, about 90 minutes later, according to the Pierce County Sheriff’s Department. No passengers or crew appeared to be aboard the 76-seat plane.
Horizon Air COO Constance von Muehlen said in a late-night video that “our hearts are with the family of the individual onboard as well as all our Alaska Air and Horizon Air employees.”
She said she believed the plane had been taken by “a single Horizon Air employee” and that no other passengers or crew were onboard. The employee was a “ground service agent,” according to Alaska Airlines.
