who was red john

Red John was the primary antagonist and a notorious serial killer in the CBS crime drama "The Mentalist." His killing spree, believed to have started in 1988, involved murdering more than 70 people across California, Nevada, and Mexico. He is infamous for murdering the wife and daughter of Patrick Jane, the show's protagonist, which fueled Jane's quest to capture him. Red John was not just a lone killer but had a cult-like network of operatives and followers who worshipped him and carried out his plans. His identity was kept mysterious for many seasons, with several false leads until finally revealed in season 6 as Thomas McAllister, the sheriff of Napa County. McAllister was the founder and leader of a secret organization called the Blake Association. Red John's modus operandi included leaving a smiley face symbol in blood at his crime scenes. His character represents more than a villain; he embodied systemic evil with deep connections in law enforcement and a network of brainwashed followers who carried out his murders and protected his identity.
