Travis Decker is accused of killing his three young daughters, whose bodies were found near a campground in central Washington.

DNA profiles matching that of Decker were found on the plastic bags that were used to suffocate Evelyn, 8, Paityn, 9, and Olivia Decker, 5.

DNA testing has confirmed Travis Decker, a Washington state father accused of killing his three daughters in June, is the sole suspect in the murders, authorities said Tuesday.
