Leon McAffrey was born and raised in Liberty City who, at some point, joined the Liberty City Police Department, later becoming a corrupt officer and making contact with Salvatore Leone, the Don of the Leone Family, eventually going on Salvatore's payroll.
He apparently killed some of his former partners, including one who had a wife and children. He also had contacts in Italy from whom he gathered information from.
In 1998 he had a dispute with Ned Burner who owed him money. According to Leon, Ned had agreed to pay him $20,000 for an unknown favour, but only paid him $5000 in the end. As a result of this, he sent Ned an e-mail in which he threatened to kill him and get away with it because of his position in law enforcement. Ned argued that the $20,000 they agreed to was in exchange of four stories for him to publish, whereas Leon had sent him only one, which was his reason to give him $5000 instead of $20,000 to keep in proportion.
He is introduced to and employs Toni Cipriani to kill the Sindacco Family members, lure the Forelli Family into an ambush with the Uptown Yardies, fight organized crime in Belleville Park, help the Uptown Yardies hold on to Newport and destroy Forelli weapons being transferred to a new location.
Following the arrest of Salvatore Leone, Leon phones Toni to say that the two never met, cutting ties with the Leone Family.
McAffrey continues to work with the LCPD and with his new partner, Ray Machowski, a law abiding police officer who eventually also becomes a corrupt officer. His crimes and links with organized crime become evident to the LCPD and he agrees to turn states evidence against Machowski, now working for the Yakuza. When he learns of this, Machowski sends Claude to kill him, but McAffrey somehow survives and is taken to the hospital. When Ray learns that Leon survived, he instructs Claude yet again to kill him, this time succeeding.
