Story time

So I was talking to one of my teachers, and apparently she was dog sitting one day. She showed up to the house on the first day, finds the dog dead on the floor, right? So she's got to take the dogs corpse to the vet so they can dispose of it or whatever. So she goes looking for something to pack the corpse in, only she can't find anything, so she finally just stuffs it in a freaking suitcase. She doesn't have a car, so she had to take the subway to get around through NY to the vet. So this guy sees her struggling to carry the suitcase at the subway station, so he offers to help her. Then he asks her something like "this is pretty heavy, what's in it?". She tells him "it's just some computer things". Next thing you know BAM, the guy PUNCHES HER IN THE FACE, and runs off with the suitcase...

So my question is, where exactly is the guy going to pawn a dead dog?
