While both murder and manslaughter involve homicide, the charge of murder is imposed when the defendant is alleged to have acted “purposely” or “knowingly’ in causing the victim’s death. Conversely, manslaughter is charged when the defendant acts recklessly in causing the victim’s death (or consciously disregarding a substantial risk of serious bodily injury or death) or commits a homicide that would normally be charged as murder but the defendant acted in the “heat of passion” due to a “reasonable provocation”.
