A family reported seeing fugitive murder suspect Travis Decker last weekend in an Idaho forest, 400 miles from where he was last known to be.

Authorities are investigating after a reported sighting of Travis Decker in Idaho, over a month since his three daughters were found dead at a campground outside Leavenworth, Wash.

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.
