The Washington state father wanted for the alleged killings of his three daughters may no longer be alive in the remote wilderness, according to local authorities. 

Travis Decker, 32, is accused of murdering his three daughters – Paityn, 9, Evelyn, 8, and Olivia, 5 – after their bodies were found near Decker’s abandoned vehicle in a remote campground. 

In a statement released Monday night, the Kittitas County Sheriff’s Office revealed “there is no certain evidence that Decker remains alive or in this area” but insisted authorities are continuing to search for the father throughout Teenaway Valley, Liberty, Lauderdale and Blewett Pass.

Officials previously quashed a TikTok video reportedly circulating showing Morrison announcing Decker’s arrest following a long standoff. 

“To be clear, Mr. Decker is not in custody and CCSO had no part in making the video,” the department wrote in a Facebook post. 

The U.S. Marshals Service has taken on the role of lead agency in the extensive hunt for Decker. The Washington National Guard, Border Patrol, FBI, U.S. Forest Service, Homeland Security Investigations and National Parks have also reportedly joined a swath of local law enforcement agencies as the search continues, according to Fox 13. 

Authorities warn that Decker should be considered armed and dangerous but insist they have no reason to believe he is a threat to public safety. He is charged with three counts of aggravated first-degree murder and kidnapping.

The U.S. Marshals Service is offering a $20,000 reward for any information leading to Decker’s arrest. 

“We recognize we do have a job to do,” Morrison said. “If we fail, the voices of Paityn and Evelyn and Olivia will not be heard, and that’s not going to be acceptable.”
