Nine days later, Zywicki’s body, stabbed and possibly strangled, was found nearly 500 miles away in Missouri. She had been wrapped in a sheet and blanket and bound in duct tape.

These include the blanket, sheet, and duct tape Zywicki was wrapped in, shoelaces found at the scene, and other items that investigators believe could contain the killer’s DNA. So far, they have only found DNA in one item — a beer can found near where Zywicki’s car.
