Decker may have been initially traveling on the Pacific Crest Trail, officials said. In mid-June, investigators said they believed they spotted Decker as a lone hiker in the Enchantments, a mountainous hiking area in Leavenworth, Washington.

The search had drawn a significant response from federal, state, and local agencies after the tipster described a man matching Decker’s description exhibiting odd behavior on an ATV trail not commonly used by hikers.
