Looks like a decomposing otter? 
It does have that otter-ish face, and canines. A raccoon's face is too sharp.
DNA can sort it out.
Chances are you find new species in the Rainforests, not in Long Island. Although, you do have people who are breeding animals of the same family, genus together, like Pumas and leopards, or ocelots and Pumas or Ocelots and leapords, the latter creating very short legged long bodied spotted animals. As such, people are trying to create their own species, but many are sterile.
