surrendered to detectives with the Sussex County Prosecutor's Office Thursday night and transported some 250 miles to the Byram Township Police Department, where he was processed and fingerprinted, according to Gregory Mueller, Sussex County's first assistant prosecutor. He was then transferred to the Morris County jail.
Authorities have said the two soldiers met in Watertown, New York, on Dec. 18 to exchange vehicles. A dispute between the two men may have played a role in Mellish's decision to abduct Harris and take him on a more than 300-mile trek south to Brooklyn, Mellish's hometown, according to Mueller.
For reasons police haven't yet explained, Mellish then drove across New Jersey, made his way to the end of Ross Road in Byram and left Harris' body there. Prosecutors so far haven't disclosed a motive for the alleged killing.
