Alistair was born on 13/06/1994, He was born into a wealthy middle-class family, Alistair was a bookworm growing up and enjoyed his own company. He has a younger sister
Cara Mckenzie who he was very close to as a child however as they got older they became very different and Cara was always jealous of Alistair being the favourite child. Cara and Alistair had little to no relationship with their parents as they were sent off to boarding school at a young age and only spent six weeks of the year at home. Due to this Alistair buried himself in schoolwork whereas his sister became rebellious.
After graduating from Royal Alexandra boarding school at the age of 18 Alistair then enrolled at St Andrew's University, at the same time Cara left the UK and moved to America which resulted in the siblings not speaking as Alistair resented her for leaving.
Alistair studied History and law during his time at St Andrew's however soon became fed up and decided to take his trust fund and backpack around the world with his friends, during his time travelling Alistair spent his time partying and quickly started to realise that his whole life had been dictated to him and he had never made decisions for himself, he proceeded to travel for three years visiting places such as Thailand, Australia and Europe.
Upon returning home he was advised that his father had cut him off from the family fortune and no longer recognised Cara and Alistair as his children, due to this Alistair decided to turn to the one person he had left and traveled to Los Santos to find his sister to rebuild as he now understood why she left.
