Marshals said the man, who fit Travis Decker's description, was surprised to be targeted by officials in Idaho as a potentially wanted man.

Travis Decker, the Washington state man wanted in connection with the deaths of his three daughters, was possibly spotted in Idaho over the weekend.

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.
