Highway of Horrors

what happens

College student Tammy Zywicki vanishes in 1992 after her car breaks down on the highway. Family and friends scramble to find her, but when her body is found 500 miles from where she vanished there are very few clues pointing to her killer. Police struggle with dead-end leads and suspects who don't pan out. New DNA technology promises to finally crack the case decades later. As her family clings to the last of their hope, the fear is that it may be too little too late for justice.
