Hiker found dead on Mount Si trailhead

A hiker was found dead on the Mount Si trailhead on Tuesday evening, according to the King County Sheriff’s Office.

Deputies received a 911 call just after 5 p.m., reporting an unconscious male hiker near the top of the Mount Si trailhead. The callers told deputies that they had seen the man a short time earlier and when they came back, he was on the ground and unconscious.

The hikers reportedly performed CPR on the man and called 911. Around 6 p.m., the man was pronounced dead at the scene.

Authorities don’t know whether the man, who was believed to be in his 50s, had a medical issue or if something else may have caused his death.

Search and rescue teams were called to the scene to recover the victim and carry him back down from the mountain, the sheriff’s office said.
