For a conviction of murder with actual intent, the court must be satisfied beyond reasonable doubt that either: (a) the accused desired to bring about the death of the victim and succeeded in completing that purpose; or (b) while pursuing another objective, the accused foresaw the death of the victim as a substantially certain result of that activity and proceeded regardless. Intention can be inferred from objective circumstances including: the nature and severity of the weapon used, the degree of force applied, the depth and location of wounds inflicted on vital parts of the body, the accused's conduct after the offense (such as fleeing), and whether the accused was prepared with the weapon beforehand. Where two consistent eyewitnesses provide clear testimony contradicting an accused's version of events, and the accused's version is objectively implausible and inconsistent with the physical evidence (such as the depth and nature of wounds), the court is entitled to reject the accused's version and convict based on the state's evidence. On causation, the state must prove both factual causation (but for the accused's conduct, the deceased would not have died when he did) and legal causation (it was objectively foreseeable or within the range of ordinary human experience that the accused's action would lead to death).
