Rule of Law:
A defendant's conduct constitutes the legal cause of a victim's death if the conduct was a substantial factor in bringing about the death, even if it was not the sole or immediate cause.
Facts:
- Lee S. Matthews and his stepson, James Marchadie, were next-door neighbors with Dorothy A. Pennino, with whom Matthews had previously had an affair that he had ended.
- Following the breakup, Pennino frequently engaged in arguments and vulgar shouting matches with Matthews' family.
- On the night of June 29, 1980, Matthews and Marchadie decided to beat Pennino to make her stop the harassment.
- Matthews lured Pennino into his car under the false pretense of a romantic encounter and drove to a secluded spot along the Intracoastal Waterway, while Marchadie hid in the vehicle.
- At the location, both men struck Pennino, and Matthews hit her in the back of the head, causing her to fall.
- Matthews then knelt on Pennino's back and smashed her face into the concrete several times, rendering her unconscious.
- Matthews and Marchadie placed the unconscious victim on a steep slope between the highway railing and the canal.
- The next night, Pennino's body was found floating in the canal, and an autopsy determined the cause of death was drowning.
Procedural Posture:
- Lee S. Matthews and his stepson, James Marchadie, were originally charged with the murder of Dorothy Pennino.
- Marchadie pled guilty to manslaughter and agreed to testify at Matthews' trial.
- In a prior pre-trial proceeding, the Supreme Court of Louisiana granted Matthews' motion to suppress certain inculpatory statements.
- After a trial by jury, Matthews was found guilty of second-degree murder.
- The trial court sentenced Matthews to life imprisonment at hard labor without the possibility of parole, probation, or suspension of sentence.
- Matthews (appellant) appealed his conviction and sentence to the Supreme Court of Louisiana, where the State of Louisiana was the appellee.

Issue:
Does a defendant's act of beating a victim into unconsciousness and leaving her on a slope next to a body of water, where she subsequently drowns, constitute a legally sufficient cause of death to support a second-degree murder conviction?
Opinions:
Majority - Marcus, J.
Yes. A defendant's conduct is the legal cause of death if it was a substantial factor in bringing about the result. The court reasoned that although the immediate cause of death was drowning, Matthews' acts of beating the victim into unconsciousness and leaving her in a perilous position on a slope directly above the canal were a clearly contributing cause. This conduct was a substantial factor in her death, regardless of whether she rolled, crawled, or stumbled into the water. Therefore, the evidence was sufficient for a rational trier of fact to find that the state proved the essential elements of second-degree murder beyond a reasonable doubt, including both specific intent to inflict great bodily harm and causation.
Analysis:
This case solidifies the 'substantial factor' test for legal causation in Louisiana homicide jurisprudence. It establishes that a defendant cannot evade criminal liability by arguing that an intervening force was the immediate cause of death if that force was a foreseeable consequence of the defendant's felonious act. The decision prevents defendants from escaping a murder conviction on a technicality when their actions create a zone of danger that directly leads to the victim's death. This precedent is crucial for cases where a defendant's violence sets in motion a fatal chain of events, even if the final cause of death is environmental or indirect.
