A skydiver is missing after he jumped from about 2,000 feet Thursday near Mt. Si and didn't show up at the landing site.
King County Sheriff's Office spokeswoman Sgt. Cindi West said via Twitter that search and rescue teams were on the way at about 3 p.m.
The man, one of three who had chartered a helicopter for the jump, was wearing brown and green clothing, which made the search more difficult, especially as it grew dark, KOMO News reported.
The helicopter pilot didn't know if the man's parachute opened, according to The Associated Press.
