Authorities who have spent the past three weeks searching in the mountains of Washington state for an ex-soldier wanted in the deaths of his three young daughters say there is no evidence that he remains in the area or that he is alive at all.

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.

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