The search for the Washington father alleged to have murdered his three young daughters has widened, as both federal and state law enforcement officers intensify their efforts in the thick wilderness to locate the survivalist with military training.

This week, authorities announced that they are thoroughly searching the areas of Teanaway Valley and Blewett Pass as the hunt for Travis Decker enters its third week, according to updates from the Kittitas County Sheriff’s Office.

The department urged, “Please review your trail cameras or doorbell cameras for any unusual activity. If you own property in these locations, examine it for anything missing, regardless of how minor or seemingly inconsequential it may seem,” in their statement.

Officials also quashed a TikTok video reportedly showing CCSO Sheriff Mike Morrison announcing Decker’s arrest after 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 hunt for Decker, who is a former member of the military with extensive experience in wilderness survival. The Washington National Guard is also assisting local law enforcement with aerial search efforts and surveillance.

Officials warn that Decker is considered armed and dangerous but do not have reason to believe he is a threat to public safety. 

The U.S. Marshals Service is offering a $20,000 reward for information leading to Decker’s arrest. He is charged with three counts of aggravated first-degree murder and kidnapping.
