The Chelan County Sheriff’s Office has issued a community alert for the area of Ingalls Creek and Valley High as law enforcement searches for suspect Travis Decker.

Travis Decker is accused of suffocating his daughters during a recent camping trip in Washington. Authorities say the Army veteran is "well versed in wilderness survival" and considered dangerous.

SEATTLE (AP) — Authorities say they believe they spotted Travis Decker, an ex-soldier wanted in the deaths of his three daughters, in the remote backcountry of Washington state, after receiving a tip from hikers who said they saw a lone person who appeared to be ill-prepared for the conditions.

The Chelan County Sheriff's Office reports tracking teams believe Travis Decker is in the Blewett Pass/Highway 97 area. Anyone in the reported area is asked to remain on alert and report any suspicious activity.

The search gained new momentum after a hiking group reported seeing a lone hiker in the Enchantments who appeared to be unprepared for the terrain and weather and seemed to be avoiding contact with others.

As the manhunt continues for Travis Decker, the father suspected of killing his three young daughters in Washington state, officials are releasing more information about what was found at the crime scene.

Law enforcement believes the man wanted for murdering and kidnapping his three daughters has been tracked to the Blewitt Pass area.

Results of autopsies for the three girls killed at a remote campsite, about 18 miles west of Leavenworth last weekend, revealed the cause of death was suffocation, and the manner of death is now officially being called homicide, according to the Chelan County Sheriff’s Office.

The Chelan County Sheriff’s Office announced Monday it has handed over the search for Travis Decker to federal authorities, even as sheriff’s detectives continue to lead the investigation into the killings of Decker’s three young daughters.
