Thomas Christopher Anderson, known as Tom, was 62 when he walked away from his Shoreline, Washington group home on December 27, 2010. A dependent adult with a mild intellectual disability, he required consistent care, had limited independent speech, and could not function on his own. He removed his GPS tracking device and left without identification or other personal belongings, wearing only a blue t-shirt and unknown pants despite cold weather.

Anderson is described as a white male, 5 feet 10 inches and 280 pounds, with very thin graying hair in the front, brown eyes and possibly a gray mustache. His wallet and bus pass were later found at a nearby secondhand store, but it could not be determined when it was left there. Staff searched transient areas of Seattle and the King County Sheriff’s Office investigated, yet no confirmed sightings or leads have surfaced and he is classified as an endangered missing person.

If anyone knew Thomas, his routines, or saw him around Shoreline or Seattle in late December 2010, please contact the King County Sheriff’s Office with any information.
