National Guard mobilized to assist in the search for survivalist suspected of murdering his three young daughters

The search has intensified for a Washington state survivalist who has been on the run from authorities for more than a week after he allegedly killed his three young daughters.

Washington Gov. Bob Ferguson activated the state’s National Guard late Friday to assist in the manhunt for Travis Caleb Decker, 32, who disappeared after he failed to return his children following a scheduled visitation.

Separately, police said that more than 100 officers are now searching for Decker, with more than 500 tips coming in from the public as police said their focus on the fugitive has narrowed.

“At the request of the Chelan County Sheriff’s Office, we will be providing helicopter transportation for law enforcement as they search in remote areas,” Ferguson wrote on X.

It is unknown whether he is armed, but authorities say he should be considered dangerous.

The Chelan County Sheriff’s Office is advising anyone who sees Decker to avoid approaching him and call 911 immediately. He faces a maximum of life in prison without the possibility of parole.

Authorities are offering a reward of up to $20,000 for information leading to his arrest.
