It should be noted, however, that the two actions are not mutually exclusive; a person may be prosecuted criminally for causing a person's death (whether in the form of murder, manslaughter, criminally negligent homicide, or some other theory) and that person can also be sued civilly in a wrongful death action (as in the O.J. Simpson cases).
In most, if not all common law jurisdictions, there was no common law right to recover civil damages for the wrongful death of a person. However, now the states have each enacted statutes to create a right to such recovery. The issue of liability will be determined by the tort law of a given state.
The death must have been caused, in whole or in part, by the defendant's conduct, even though there was no direct intention to kill the victim. The defendant must have been deemed negligent or strictly liable for the victim's death. Also the deceased has dependent party such as family members who have suffered from emotional and monetary damages as a result of the death.
