A Washington state man is wanted on suspicion of murder after his three young daughters were reported missing and subsequently found dead.

Travis Decker, aged 32, is facing charges for three counts of murder and kidnapping, as reported by Wenatchee Police. Wenatchee is approximately 100 miles east of Seattle.

Police said it was unknown whether Decker was armed. He is a former Army soldier with “extensive training.”

As per the police, on Friday, the girls’ mother informed authorities that their father failed to bring them back after a scheduled visit. The ages of the girls were nine, eight, and five.

“She decided to contact us because… he was late in bringing the girls back and hadn’t informed her about the delay, which was unusual since he typically would,” explained Capt. Brian Chance.

The sheriff’s office, which located the truck, was leading the search in the Okanogan Wenatchee National Forest area while other teams followed up on “potential credible information and tips” about Decker’s location, the agency said in a statement.

The agency was working with U.S. Marshals to search for Decker. A reward of up to $20,000 was available for information leading directly to his arrest.

“Travis, if you’re listening, this is your opportunity to turn yourself in,” Chelan County Sheriff Mike Morrison said at a press conference Tuesday. “Do the right thing, do what you need to do. And take accountability for your actions. We’re not gonna go away, we’re not going to rest, and we’re gonna make sure we find you.
