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

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.

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.
