Remains believed to be Travis Decker, the 32-year-old father accused of murdering his three young daughters near a Washington campground, were located in a remote wooded area, according to the Chelan County Sheriff’s office.

“While positive identification has not yet been confirmed, preliminary findings suggest the remains belong to Travis Decker,” the sheriff’s office said Thursday evening.

Decker, an Army veteran, was wanted for three counts of first-degree murder and three counts of first-degree kidnapping, police said.
