Federal investigators are continuing to study the remains of the airplane that crashed the night of Oct. 7, killing the pilot and nine sky divers. The plane went down in the White Pass area.

The group of sky divers was aboard a single-engine Cessna 208B Grand Caravan owned by Kapowsin Air Sports based in Shelton. They were returning from a trip to Star, Idaho, near Boise. A hunter in the area reported noticing a low-flying plane with possible engine trouble, then heard a crash. The plane was found 45 miles west of Yakima at about 4,300 feet elevation. Investigators said the plane had turned around before hitting the ground.

Most of the sky divers were reported to be active in the sky diving community at Harvey Field in Snohomish.

Casey Craig of Bothell was among the dead. Other victims were Jeff Ross, Landon Atkin and pilot Phil Kibler, all of Snohomish, Bryan Jones of Redmond, Andrew Smith and Cecil Eisner of Lake Stevens, Michelle Barker of Kirkland, Hollie Rasberry of Bellingham and Ralph Abdo of Issaquah.

A memorial service is planned to take place at Harvey Field but a date has not yet been set.
