I haven't seen anything about this case on here or the Doe Network but it caught my interest looking through local newspaper archives.
On June 24, 1989 legs, arms, and a torso were found off of a rest stop on Route 78 in Warwick, MA, just 1 mile from the New Hampshire border. The parts were originally thought to be from a man in his 30s (most newspapers reported this) but later studies suggested that the parts are actually from a woman. She was white, approximately 5'5" and "robust". The other parts of the body including the head were never found. The body was badly decomposed but I don't think authorities were exactly certain of when the victim died.
Newspapers reported that there was a concern about this being related to a cult or other ritualistic killing. Two corpses of headless dogs were found approximately 25 feet from the human remains. Many people in Worcester county also reported that their pets went missing around the same time (the body was left in Franklin county, but that does boarder Worcester county). That being said, these incidents are not definitively linked to the body.
I haven't seen any updates on this case in the local media since the late '90s.
