Police releases a footage of a triple murder suspect with wilderness survival skills

Chelan County Sheriff's Office deputies released doorbell cameras and photos of 32-year-old Travis Decker, who was wanted for three counts of first-degree murder and kidnapping.

They said the videos and photos were from the days he visited with his three daughters. The video also shows what the police believe is the last known appearance.

Police said the newly obtained information showed that Decker was “proficient in the survival of the wilderness and was able to spend days or even weeks alone in the wilderness.”

“We've got more confirmation that he may have passed the Mountain Survival School,” Chilan County Sheriff Mike Morrison told reporters Wednesday. “But we also know that he's been outdoors since he was a child.

Investigators are currently working with authorities across the county and state to locate known colleagues and provide Decker's potential initiatives.

“When we took a 'all-out approach to investigating the murders of three young girls, the morale of the team was still rising as we worked to locate Travis Decker,” authorities said. “In addition, it is well known that the region is well-known that more and more teams are being deployed to different locations.”

Police said that while the challenge of finding Decker was a challenge, their personnel assured the public that they were ready to arrest him.

The Chelan County Sheriff’s Office said: “The U.S. Pacific Northwest Violent Criminals Task Force is working closely with the Chelan County Sheriff’s Office to find and arrest the fugitive” and receive a reward of up to $20,000 to directly lead to Decker’s arrest.

It added: “The suspect is not currently armed but should be considered dangerous.”

The three girls, five, eight and nine, went to their father on Friday, May 30 for a planned visit, and later found their bodies on Monday afternoon near Decker’s abandoned pickup truck.

The mother told police he told police that Decker picked up the girls around 5 p.m. Friday but did not send them back by 8 p.m., court documents said, and his phone was sent directly to voicemail.

One detective said she “expressed concern because Decker reportedly had never done this before and… is experiencing some mental health problems right now.”

“What prompted her to call us was…he was late for the girl and didn't communicate to her that he was late for him, which was typical fashion for him, so it was different.”

According to court documents, police believe the girls had zippers tied with wrists and died of suffocation.

Sheriff Morrison reiterated his request for Decker on Wednesday.

“Travis, if you meet us there, we hope you can hand in yourself,” Morrison said in a press conference. “We hope to have a peaceful solution to this, but we will not give up on our efforts and give up on anything that can track you. So, arrange yourself. Let's work. Let's wrap up and do what's right for your child.”
