Sealy (D) failed to stop his car at a stop sign and killed two people. He was indicted for criminal negligence involuntary manslaughter. The jury was given two instructions: (1) Involuntary manslaughter could result from an intentional violation of a statute designed to protect human life when the violation was the proximate cause of death. (2) Involuntary manslaughter could result from a violation of the statute prohibiting the running of stop signs when that violation was the proximate cause of death. D was convicted. D appealed; the jury instructions were conflicting.
