Petto v HM Adv 2012 JC 105
facts: Petto had murdered his flatmate. They lived on the ground floor, and to cover up what he had done, he decided to light his body on fire. This fire spread to the rest of the block, causing one of the upstairs residents to die from smoke inhalation.
legal issue: The accused didn’t intend to injure the person in the upstairs flat.
held: While wicked recklessness requires intention to cause injury, however intention includes foresight that the accused’s conduct was virtually certain to cause injury.
significance: Intention for the purpose of wicked recklessness can include indirect intention.
