Facts

Appellant took custody of Shirley Green's two children, including Anthony Lee, who was released from the hospital to appellant's custody shortly after birth and remained with her until police removed him. The evidence showed Anthony Lee was severely malnourished, weighed only seven pounds thirteen ounces at ten months, had lesions on his body, and died 34 hours after hospital admission; the cause of death was undisputedly malnutrition. There was evidence that appellant had consulted a doctor and once took the child to the doctor, but the doctor had recommended hospitalization a month before the child's death and appellant did not take him to a hospital or obtain further medical care. The evidence conflicted on whether appellant had agreed to care for Anthony Lee for compensation or whether the mother was living with appellant and remained responsible for the child.

Issue

In a prosecution for involuntary manslaughter based on failure to provide food and medical care, must the jury be instructed that it must first find beyond a reasonable doubt that the defendant was under a legal duty to care for the child? Also, was there sufficient evidence to let the jury decide whether appellant failed to feed the child or obtain proper medical care?

Rule

A defendant may be criminally liable for an omission causing death only when the omitted act was required by a legal duty, not merely a moral obligation. Such a legal duty may arise in at least four situations: where a statute imposes a duty of care, where a status relationship exists, where the defendant has assumed a contractual duty to care for another, or where the defendant has voluntarily assumed the care of another and secluded the helpless person so as to prevent others from rendering aid. Because legal duty is a critical element of the crime, the jury must be instructed to find that duty.

One of 10 multiple-choice questions for this case. Pick an answer to see why.

In Phoenix, Lena Ortiz occasionally brought groceries to her elderly neighbor, Carl Benton, who lived alone. One evening she saw him trembling and unable to stand, decided she was too busy to help, and left; he died overnight from dehydration.

If prosecutors charge Lena with involuntary manslaughter based solely on her failure to assist Carl, which is the strongest argument for acquittal under the governing rule?

Explanation. The governing rule is that homicide liability based on an omission requires a legal duty to act, not a mere moral obligation. The majority identifies four possible duty sources: statute, status relationship, contract, or voluntary assumption of care plus seclusion. On these facts, casual neighborly assistance alone does not establish such a duty.
