Travis Decker is wanted in the deaths of his daughters, who were found near a campground east of Seattle after he failed to bring them home from a visitation.

Authorities say blood discovered at a campsite where three young Washington state sisters were found dead last week belonged to a male.

Paityn Decker, 9; Evelyn Decker, 8; and Olivia Decker, 5, were located on June 2 near the Rock Island Campground in Chelan County, Washington, police said.
