Authorities in north-central Washington State late Thursday said they have found human remains they believe belong to Travis Decker, the man they have been hunting for months following the deaths of his three daughters.

The discovery of the human remains follows a months-long search for Travis Decker, who was 32 years old when he disappeared.

The Washington father has been on the run since early June , after he allegedly suffocated his daughters, Paityn, 9, Evelyn, 8, and Olivia, five, to death.
