(NewsNation) — Local, state and federal authorities are searching for Travis Decker, a Washington state man they believe killed his three young daughters.
The sisters — ages 5, 8 and 9 — were found around 4 p.m. Monday near Decker’s vehicle close to a campground west of Wenatchee, Washington. Their mother had reported them missing on Friday after Decker failed to return them from a planned visitation.
Police believe the girls died from asphyxiation, according to court documents. They were allegedly found with their wrists zip-tied.
Decker, who police said is homeless, is wanted for three counts of first-degree murder and first-degree kidnapping.

Travis Decker could stay in wilderness for months: Dad
Chelan County Sheriff Mike Morrison told NewsNation Decker’s background could benefit him in the area’s mountainous terrain.
Morrison said Decker’s father told investigators that his son had enjoyed spending time in the wilderness since childhood, sometimes for months at a time, and was known to cache supplies in remote areas.
“If he did set it up beforehand and put supplies out there, it could make it more difficult to track him down,” Morrison said.
