I hate to be such a dick about this but:
n. the crime of causing the death of a human being due to illegal driving of an automobile, including gross negligence, drunk driving, reckless driving or speeding. Vehicular manslaughter can be charged as a misdemeanor (minor crime with a maximum punishment of a year in county jail or only a fine) or a felony (punishable by a term in state prison) depending on the circumstances. Gross negligence or driving a few miles over the speed limit might be charged as a misdemeanor, but drunk driving resulting in a fatality is most likely treated as a felony. Death of a passenger, including a loved one or friend, can be vehicular manslaughter if due to illegal driving.
It's really up to the judge to decide whether or not this is the crime commited. But since there would be no malice aforethought and a DUI death would lack any pirior intention of the death of an individual there is a small chance of a judge stating that this is murder.
edit: Sorry if I have offended anyone, I know that DUIs are very touchy around here.
