FBI confirm chilling discovery in search for dad accused of killing three daughters

Police have confirmed what some of the items discovered during a search relating to Travis Decker were.

Decker is accused of murdering his three young daughters, whose bodies were discovered in early July.

Decker collected the girls from his ex-wife's house on May 30 as planned but failed to return them home the same day.

Tragically on July 2 the bodies of the girls, aged five, eight, and nine, were found at the Rock Island Campground in Leavenworth.

Decker has been charged for the murder of his daughters but remains at large.

An initial search at the campsite was carried out around the time the Decker girls were discovered, and the FBI recently conducted another 48-hour search.

Almost 250 acres were covered during the inquiry with the help of over 100 people.

"A search of this magnitude and detail has not previously taken place in this area," the FBI shared in a statement issued on August 29.

It continued: "We not only accomplished our goal of covering the entire area intended for this operation, but we also searched beyond the primary search perimeter. The electronic mapping of this search effort is being provided to the Chelan County Sheriff's Office and our federal partners."

'Several items' went on to be found at the site that could relate to the investigation.

Mike Herrington, special agent in charge of the FBI Seattle field office, said that items are being examined and that it may 'take some time' for the results to come in.

It's since been revealed that some of the items found included bones.

Sheriff Mike Morrison confirmed to The Wenatchee World: "The bones were found during the grid search by one of the 100 personnel. It was inconclusive at the time if they were animal or human, so it was sent off to Central Washington University in their anthropology department to do a confirmation."

While it's been almost two months since the girls' bodies were found, Morrison insisted that they 'have not lost sight of the importance of this case'.

"We are trying our best to make sure that this does not just disappear and fade away into memory," he added.

Morrison expects that 'we'll have another effort coming here in September' in the wake of the most recent two-day search reaping some results.
