Hans Thomsen, 59, disappeared from Anchorage in early September 2003. He was last seen on September 6; a welfare check was reported to police on September 8 and the Anchorage Police Department opened a missing person investigation. Thomsen is described as a Caucasian male, graying hair, blue eyes, five feet nine inches tall and about 180 pounds.

The most notable piece of evidence turned up on October 12, 2003, when Thomsen’s bicycle was found abandoned on the Indian Creek Trail. That discovery shifted the search to the trail and surrounding wilderness and prompted assistance from the Alaska State Troopers, but no further clues emerged. There were no signs of foul play at his home, and investigators report no significant breakthroughs since.

The case remains open; the bicycle on the trail is the last known trace of Hans Thomsen. Does anyone who knew Thomsen or frequented the Indian Creek Trail that September have information that could help?
