() The FBI provided an update on the search for alleged killer Travis Decker, stating they have no evidence to conclude he is alive or dead.

For almost three months, the FBI and the Chelan County Sheriff’s Office have been searching for Decker, who is alleged to have killed his three young daughters: Paityn Decker, 9; Evelyn Decker, 8; and Olivia Decker, 5.

Their bodies were found near the popular Rock Island campground in Leavenworth on June 2. The search has been ongoing for Decker, with Sheriff Mike Morrison admitting it has been frustrating, but the agency, U.S. Marshals and his office have not given up.

FBI leading search of campground

In an order shared by the Forest Service, the campground where the girls were killed will be closed Sunday, Aug. 24, until Wednesday, Aug. 27, at 6 a.m. local time.

The campground will be searched for two more days, canvassing a quarter-mile radius around the campsite, according to Morrison.

It has already been searched, but authorities are combing through the area in an attempt to gain further information on Decker’s whereabouts.

It comes days after DNA matching Decker and his three daughters were the only profiles found at the scene of the girls’ deaths.

Analysis from the Washington State Crime Lab found Decker’s and his daughters’ DNA on objects used in the killings.

Sheriff Morrison wants justice

“We want to bring closure, we want to bring answers. We understand the frustration; we’re feeling it as well,” Morrison said.

“We would love to have Travis Decker in custody, standing in front of a judge,” he added.

Morrison noted the Rock Island campground is the primary area of focus given the location of the killings and behavioral analysis.

“It’s going to take us some time, and we’re going to continue to do a thorough search and continue to expand out around the initial crime scene and make sure we didn’t miss anything,” he said.

“I believe we did a thorough search initially, but when we come back with new technology, more resources, more personnel, that allows us to better document what we have covered for future investigations,” he added.
