## Facts

- Michael Daniel Sargent, Sr. was caring for his infant son, born three months premature and developmentally fragile.
- Emergency responders found the infant on the apartment floor in a deep coma, not breathing and without a heartbeat, with blood from his nose and mouth; the child was resuscitated and hospitalized.
- Sargent gave shifting explanations, initially claiming the child fell from a couch and later claiming he dropped the child during play.
- After being confronted with medical opinions consistent with “shaken baby syndrome,” Sargent admitted shaking the infant four or five times “more hard” while the child sat in a car seat, causing the child’s head to lose contact with the seat.
- Medical testimony indicated the injuries were consistent with severe shaking and inconsistent with a short fall.

## Issues

1. Under former Penal Code § 273a(1) (now § 273a(a)), what mens rea is required for felony child abuse based on directly inflicting “unjustifiable physical pain or mental suffering” under circumstances likely to produce great bodily harm or death?
2. Does felony liability on a direct-infliction theory require proof of criminal negligence, or is “willfully” satisfied by general intent to commit the act?

## Decision

- The California Supreme Court reversed the Court of Appeal and reinstated the felony child abuse conviction.
- The court held that criminal negligence is not required when the prosecution proceeds on a direct-infliction theory under former § 273a(1).
- The statutory term “willfully” supplies the mens rea and requires only that the defendant intentionally commit the act that inflicts unjustifiable pain or suffering, not that the defendant intend injury or be shown criminally negligent as to risk.
- Because Sargent admitted intentionally shaking the infant forcefully and the circumstances were likely to produce great bodily harm or death, the evidence supported the felony conviction without additional proof that he knew or should have known the degree of medical risk.

## Legal Principles

- For felony child abuse under Penal Code § 273a(a) based on directly inflicting unjustifiable physical pain or mental suffering, “willfully” denotes general intent: an intentional act, not an accident.
- Criminal negligence is not an element of § 273a(a) on a direct-infliction theory; it has been associated with endangerment/omission theories where courts supply a mental-state requirement for non-infliction conduct.
- The prosecution need not prove a specific intent to injure or a heightened awareness of risk beyond the intentional commission of the abusive act under circumstances likely to produce great bodily harm or death.

## Conclusion

The court held that felony child abuse predicated on directly inflicting unjustifiable physical pain or mental suffering under § 273a(a) is a general-intent offense satisfied by an intentional act, and it rejected a criminal-negligence element for that theory of liability, thereby reinstating Sargent’s felony conviction.
