DUI accidents that result in death attract the harshest penalties such as lengthy prison sentences and hefty fines. This is a guarantee especially if the driver that caused the accident was impaired by alcohol or drugs (illegal or prescription medication). A motorist can be convicted of vehicular homicide if the accident they caused while impaired resulted in death or great bodily harm and certain other conditions were met (see video below). Vehicular homicide is a felony in Louisiana.
A prosecutor only needs to prove that you were intoxicated when you caused the accident for you to get convicted. That means that defense arguments like lack of intent to cause harm cannot get you out of trouble. Only a highly trained attorney may be in a position to help defeat the case against you.
