William Cobb, a 33-year-old Boston man, has been arrested on three counts of animal cruelty after three dogs were found dead in an abandoned U-Haul van in Mattapan. The investigation began when police received a 911 call about a terrible smell coming from the van, which had reportedly been parked on Edgewater Drive for several days. Witnesses reported seeing the dogs alive as recently as July 4th and observed suspicious activities around the van, including individuals with cleaning supplies and a man pouring water on the dogs. The dogs' deaths are believed to be linked to the extreme heat, as temperatures in Boston reached above 90 degrees. Authorities are asking anyone with information to contact Boston police as the investigation continues.
