The accused was charged with manslaughter following the death of a 17-year-old victim whose body was found in a park.
The victim died from hypothermia, blunt facial trauma, and ethanol intoxication.
The Crown relied on circumstantial evidence, including video surveillance and DNA, to prove the accused assaulted the victim before leaving him in freezing temperatures.
The defence argued the police investigation was flawed and pointed to alternate suspects.
The court rejected the alternate suspect theories, finding the circumstantial evidence excluded any other reasonable alternative to the accused's guilt.
The court concluded the assault was a substantial contributing cause of death and found the accused guilty of manslaughter.
