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

Law enforcement has initiated a joint search in Idaho's Sawtooth National Forest for Travis Caleb Decker, wanted for the murders and kidnappings of his three children in Washington state. The intensified search follows a recent tip reporting a possible sighting of Decker by a family in the Bear Creek area of the forest on Saturday.

Marshals said they are beginning to receive tips from the public, are checking each one, and hope one of the tips will help catch Decker.
