DNA analysis confirms Travis Decker as sole suspect in daughters' killings while U.S. Marshals offer $20,000 reward for information on his whereabouts.

Authorities said DNA testing has confirmed that the sole suspect in the killing of three young girls in Washington state over two months ago is their father, who has still not been located.

The Washington State Crime Lab completed an analysis showing DNA profiles found at the crime scene matched Travis Decker's.

The Chelan County Sheriff’s Office says new DNA evidence directly links Travis Decker to the deaths of his three daughters, whose bodies were found in June near Icicle Creek. On June 2, deputies discovered the bodies of Paityn, Evelyn and Olivia Decker close to the Rock Island Campground.

As the search for Travis Decker has almost reached the three-month mark, officials are revealing disturbing new details about the crime scene.
