The evidence was sufficient to convict for felony injury to a child when the State showed that guardians slowly starved two boys in their care. Attempts to conceal the guardian's treatment of the boys along with testimony about the severity of the malnutrition by a hospital pediatrician permitted the jury to find the boys suffered serious bodily injury because the guardians intentionally and knowingly failed to provide them with adequate nutrition and medical care. (In a companion case, the court affirmed the husband's conviction for felony injury to a child, rejecting his complaint about admission of a videotaped interview between the boys and CPS workers.)
