The search continues for Travis Decker, a father accused of murdering his three young daughters, whose bodies were discovered in a Washington campground. Authorities have intensified efforts to locate Decker, with federal agencies taking over the manhunt. Evidence, including blood found at the campsite and alarming online searches made by Decker before the tragedy, has raised suspicions. New autopsy results reveal the sisters were suffocated, prompting a community alert and extensive searches in the Ingalls Creek area. Family members and officials have called for changes in the support systems that may have failed to prevent this tragedy.
