Rescue crews are spending their fourth straight day looking for a skydiver who vanished during a jump above Washington's Cascade foothills.
King County sheriff's Sgt. Cindi West says searchers were back out near 4,200-foot Mount Si east of Seattle at first light Sunday, hoping to find 29-year-old Kurt Ruppert of Lake City, Fla.
Ruppert hasn't been seen since he jumped out of a helicopter at 6,500 feet Thursday afternoon, wearing a special wing suit with fabric under the arms to allow him to glide like a flying squirrel.
Crews narrowed their search area on Saturday, based on data from Ruppert's cell phone and the helicopter's flight path, but still haven't found any sign of him.
