Where an accused person uses disproportionate and excessive force in response to an unlawful attack, causing injuries that lead to death, and it was objectively foreseeable that such actions would result in death, the accused is guilty of culpable homicide under section 49 of the Criminal Law (Codification and Reform) Act. Culpable homicide is established where the accused negligently failed to realize that death may result from his conduct, or realizing that death may result, negligently failed to guard against that possibility. A reasonable person placed in similar circumstances would have avoided acting in the manner the accused did. The test is objective foreseeability within the range of ordinary human experience.
