Authorities in Washington state are scaling back the search for Travis Decker, the man suspected of killing his three daughters nearly two months ago

Police in Washington will scale back their search for Travis Decker, a Pewaukee native suspected of killing his three daughters.

Despite a "decrease in leads and tips" on where Decker may be, the sheriff's office said detectives remain "actively engaged in processing evidence and will continue to follow up" on any new information they receive on the father's possible whereabouts -- including the sighting in Idaho earlier this month, which turned out not to be Decker.

Paityn Decker, 9; Evelyn Decker, 8; and Olivia Decker, 5, were found dead near the Rock Island Campground in Chelan County, Washington, on June 2, after they left home for a planned visit with their father on May 30, according to police.

Police have shared new video of Washington state fugitive Travis Decker three days before his daughters' murders.
