who were the killers in scream 2

Scream 2 features two Ghostface killers: Mickey Altieri and Mrs. Loomis (Nancy Loomis’s character, also known as Debbie Salt). The film reveals Mickey as a student-turned-serial killer who taunts Sidney and imitates the original film’s killer dynamics, while Mrs. Loomis, seeking revenge for her son Billy Loomis’s death and aiming to finish the Ghostface saga, operates as the mastermind behind the plot and finances Mickey’s actions.
