What you smoking? No one in New York is ever charged with vehicular manslaughter. It’s all an “accident”.You can even flee the scene like happened here, and if you are found you will still not be charged (leaving the scene of an accident involving injury or death is a crime but never enforced for some reason, a small traffic fine at worst). Just look, if they ever find this driver, all they’ll do is ask some questions and let them go. You can even drive drunk, kill someone with the car, flee the scene, evade capture for days, and then maybe you’ll be charged, but the charges will be dismissed anyway because now days later you being drunk cannot be definitely proven.
