Answer Summary: The Primary Killer and Accomplice
In the original Scream (1996), the masked killer is Billy Loomis, motivated by revenge after his mother abandons him; he is assisted by his girlfriend Stu Macher. Additional copycat attacks are carried out by the seemingly innocent Sidney Prescott’s classmate Cotton Weary. The film carefully reveals Billy’s central role through evidence, red herrings, and the final confrontation, making the identity and motive clear without relying on random twists.
Context: Setting and Franchise Pattern
Scream refreshes the horror genre by openly discussing slasher rules while delivering them. The identity of the killer is central to its plot and a key reason the film remains influential. Understanding how clues point to Billy—and why the reveal works—helps viewers appreciate the screenplay’s structure and payoff.
Primary Killer: Billy Loomis — Motive and Backstory
Billy Loomis is the mastermind behind the Ghostface killings. His motive centers on his mother, Maureen Prescott, who left him and had an affair that destabilized the family. The film presents this betrayal as the catalyst for his rage. Billy carefully plans the attacks, selecting Sidney as a target because of her mother’s history. His intelligence and manipulation allow him to orchestrate events from behind the scenes while appearing harmless.
Evidence Linking Billy to the Crime
The story provides several clues that point to Billy. He has the means and knowledge to avoid suspicion, familiarity with Sidney’s home, and a volatile emotional history. Key scenes reveal his access to information only the killer could know, culminating in a confession during the climax. These beats are reinforced by physical evidence and testimony from other characters.
Accomplice: Stu Macher — Role and Relationship
Stu Macher, Billy’s friend and Sidney’s classmate, serves as the active enforcer on the night of the attacks. He helps execute the plan, from setting up phone calls to physically confronting Sidney. Their partnership highlights how peer influence and shared grievance can empower violence. Stu’s bravado contrasts with Billy’s calculated approach, yet both are essential to the killing spree.
How Stu Participates in Key Attacks
- He answers phone calls and creates diversion during initial attacks.
- He participates in fake confrontations that lure Sidney into danger.
- He assists in staging scenes to misdirect suspicion toward others.
Misdirection and Red Herrings
Scream deliberately misleads viewers by emphasizing certain characters as possible killers. Gale Weathers, Randy Meeks, and even Sidney herself are framed as suspects through behavior, dialogue, and editing. These red herrings protect the true identity of Billy until the script allows the reveal to feel both surprising and inevitable.

Recap: Core Identification
The central killers in Scream are Billy Loomis and Stu Macher, with Billy as the planner and Stu as the active participant.
