NORWOOD, Mass. (AP) — Authorities say someone walking a dog in Norwood has stumbled upon a dead body dumped in the woods behind the Coakley Middle School.

Norfolk District Attorney Michael Morrissey says investigators are trying to determine the identity of the victim whose remains suffered massive trauma.

Morrissey and Norwood Police Chief William Brooks say there are indications that the victim was not killed at the small wooded area and investigators are searching for the primary crime scene. They ask the public for information on any location with significant blood or other indications that it may be where the killing occurred.

Authorities say the dog walker discovered the body after the pet reacted to the presence of the dead body just behind the tree line not far from the school property.

Investigators did not release additional information.
