The facts are it was an accident. No facts presented show Kennedy
killed the girl on purpose, so, it was simply an accident. Just like
the 16 year old that drove himself and 3 of his friends into a tree
and killed them all was probably an accident, not intentional, even
if he was speeding, high on grass, drunk, had a heart condition and
so on. He didn't mean to do it, so it was an accident.

Homicide is the killing of one human by the actions or inactions of another.
Classically, there are five kinds of homicide:

Murder - Intentional and premeditated
Manslaughter - Intentional and not premeditated
Negligent - Leaving a hole uncovered, drunk driving
Justifiable - Self defense, execution of a criminal or enemy in time of war,
etc.
Excusable - The rest

All five can be illustrated by considering the case of one hunter killing
another

Murder - The shooter went hunting with the intent to eventually kill his
fellow hunter.
Manslaughter - The two get into a heated argument over who shot the deer
Negligent - The bush moved and the shooter shot it
Justifiable - The victim shot at the shooter first
Excusable - The victim was dressed in a deer costume

The first three have criminal penalties, the last two do not.
