I have personally visited the spot where Teddy drove off the bridge/road.
The bridge has subsequently been torn down..
There is a tidal estuary that surrounds Chappy, and the infamous bridge crosses over a narrow area of this estuary on the way to a ferry crossing that provides access to the island from Martha's Vineyard (a much bigger island which is off Cape Cod)
If you have ever seen the bridge, and where he drove off of it, it is obvious that he must have been driving to fast (and probably was wasted), and failed to make a left hand turn onto the bridge. At a MINIMUM, you or I would have been found guilty of involuntary manslaughter, or vehicular manslaughter under Massachussetts law. He was probably drunk, and had an expire (non-valid) drivers license. This would make his crime fit the description of vehicular homicide, under the influence of alcohol, while operating to endanger....mandatory minimum sentence 2.5 years (up to 15 years) plus fines and loss of license. This would have been IN ADDITION to the crime of leaving the scene of the accident, and operating a motor vehicle without a license.
Ah...the perks of being a Kennedy in Massachussetts.....
