New Jersey Herald What was the motive behind the killing of a 20-year-old Fort Drum soldier? Why was he buried 300 miles away under snow in a secluded wooded area in Sussex County? What led authorities to charge another soldier from the same New York military base with first-degree murder? Who is the 16-year-old also charged with the murder? All these questions and more remain unanswered as the numerous agencies overseeing the case are still "piecing it together," Sussex County First Assistant Prosecutor Gregory Mueller told the New Jersey Herald. The investigation is focusing on a motive for the Dec. 19 killing of Army Cpl. Hayden Harris as well as how the suspects and the victim ended up in Byram. Was it just a random exit off Route 80 to Route 206 and eventually to secluded Ross Road, or was there a reason the area was chosen?
