## Facts

- Michael Ryczek drove a Ford automobile with companions on a highway near Saginaw, Michigan.
- At a crossroads, he drove past the corner, backed into an east–west road, and then proceeded forward; he observed another car approaching rapidly and continued across the main highway rather than turning onto it.
- About 55 feet east of the north–south highway, Ryczek’s automobile collided with a cart pulled by a boy carrying his five-month-old sister, Bernice Histed.
- The collision tipped the cart, and a wheel of the automobile ran over the infant; she died within two hours.
- The prosecution alleged Ryczek operated the automobile negligently and without excuse while under the influence of intoxicating liquor, causing the child’s death.
- The information used a statutory short-form manslaughter charge and included an additional count describing negligent, intoxicated automobile operation and the resulting death.
- A jury convicted Ryczek of involuntary manslaughter in the Saginaw County Circuit Court; he sought appellate review on questions of law before sentencing.

## Issues

1. Whether negligent automobile operation causing death may constitute involuntary manslaughter under Michigan law when supported by proof of criminal (gross) negligence.
2. Whether the statutory short-form manslaughter information, supplemented by a detailed count describing negligent, intoxicated driving causing death, adequately charged the offense.
3. Whether the evidence permitted the jury to find gross negligence (rather than ordinary negligence) and thus sustain an involuntary manslaughter conviction.

## Decision

- The Michigan Supreme Court affirmed the involuntary manslaughter conviction.
- The Court held the information was sufficient, including the statutory short form and the added detailed count.
- The Court held the evidence supported a finding that Ryczek’s manner of driving—particularly failure to keep a proper lookout, together with intoxication—amounted to gross negligence supporting criminal liability.
- The Court found no reversible error in the trial court’s treatment of the charge or its instructions.

## Legal Principles

- Involuntary manslaughter is an unintentional killing without malice that occurs while: (1) committing an unlawful act not amounting to a felony and not naturally tending to cause death or great bodily harm; (2) negligently performing a lawful act; or (3) negligently omitting a legal duty.
- Ordinary negligence is insufficient for involuntary manslaughter; the prosecution must show criminal negligence commonly described as gross negligence.
- Grossly negligent operation of an automobile that results in death can support involuntary manslaughter, particularly where the driver fails to maintain a proper lookout for obvious hazards.
- A statutory short-form charging instrument for manslaughter may be upheld when supplemented by allegations specifying the manner of operation, the victim, and the causal connection to death, providing adequate notice of the accusation.

## Conclusion

The court upheld an involuntary manslaughter conviction arising from a fatal automobile collision, concluding that the charging instrument adequately alleged manslaughter and that the jury could find criminal (gross) negligence where the defendant’s intoxicated driving and failure to keep a proper lookout caused an infant’s death.
