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.

Officials in Idaho are investigating a possible sighing of Travis Decker, the father accused of killing his three kids, after a family says they spotted the father.
