Unless you are a veterinarian, this is all bare speculation. Moreover, this seems more like efforts to rationalize the real issue, which is, how is it that your parents dog was not on a leash and hit by a car to begin with? Before you do anyhting further you will have to hire a veterinarian and have them provide a written opinion of what if anything was done improperly.
