An autistic Sammamish teen is safe and sound following a multi-agency search and rescue after he got lost while walking through a heavily wooded park.

The 17-year-old  was walking with his parents through Sammamish’s Beaver Lake Preserve park Sept. 12 when he walked ahead of his parents out of sight along a trail, according to police reports. Unable to locate the teen, the parents called 911.

Once on scene, the report states, Sammamish PD employed search and rescue resources from the King County Sheriff’s Office and the Washington State Patrol to search the 60-acre park, including aircraft with infrared scope technology.

After an approximately four-hour search, the teen was found hiding in some bushes off the side of the trail, according to police reports. Officers believe the teen, who is extremely afraid of dogs and certain bright colors, ran and hid in the bushes after seeing a dog on the trail. No injuries were reported.
