Animal Rescue League Boston’s Law Enforcement Department Wednesday said it appears the dog had not been left in the area for very long.

A necropsy found the dog’s cause of death was acute blood loss and multiple skull fractures. The dog had extensive bruising, which investigators believe indicates the dog was abused in the 36 hours before it died.
