McKenzie’s life took a dark turn three months before his 16th birthday when he became the driver in his first bank robbery. After being groomed by gangsters, he eventually started his gang and turned to a life of crime. In a previous interview, McKenzie confessed that he left his initial gang because they were only giving him small amounts of money from their heists. However, his criminal activities eventually caught up with him when he and his gang were arrested after attempting to rob a casino.
Despite facing multiple charges, McKenzie was shown mercy by a judge who saw potential for change in him. From a young age, McKenzie was exposed to the idea of killing to prove oneself in gang culture. He recalled a chilling incident where he shot a man ten times for stealing his jacket. This experience made him realize his hatred for the gangster lifestyle and its destructive beliefs.
