Jack moved to San Andreas when he was 22 as he fell out with family back in England and decided that moving in with Kapi Jackson would be a good idea. Despite his employment at Go Postal being very eventful, Jack watched his cousin, Kapi Jackson, get hired at Public Works and after riding along with him on a few of his shifts, he decided that he wanted to join Public Works too. Kapi was relatively happy about this too as it meant Jack would actually have money to pay for things, rather than rely on loans from Kapi and Alvaro Vasquez (Jack's good friend).
