Subject: Profile Correlation Between “Kevin McAllister” & Suspect Known as “Jigsaw”

Prepared By: Special Agent Caroline Vasquez

1. OVERVIEW
Recent evidence suggests a possible connection between Kevin McAllister (Chicago-based missing person, age 37) and the serial perpetrator commonly referred to as “Jigsaw.” While the original Jigsaw was identified as John Kramer, intelligence points to the existence of copycat or successor figures.

2. BACKGROUND
- Kevin McAllister gained notoriety in 1991 when, as a child, he defended his home using elaborate traps. 
- Psych evaluations from his youth highlight fascination with mechanical design and a calm demeanor under stress. 
- Multiple unsolved cases since 2015 feature elaborate “games” or contraptions reminiscent of Jigsaw’s modus operandi. Chicago PD recovered cassette tapes referencing teaching “lessons” through pain, matching the known signature of the Jigsaw killer.

3. KEY SIMILARITIES
- Tactical trap construction aligning with advanced engineering knowledge.
- Thematic emphasis on moral or personal “lessons” for victims.
- Use of audio recordings to communicate instructions or philosophies.

4. RECOMMENDATIONS
- Locate any associates of Kevin McAllister from high school and college engineering clubs for questioning.
- Cross-reference home videos and discovered cassette tapes for voice-print match.
- Monitor known McAllister family addresses and properties for booby trap setups.

5. CONCLUSION
Although speculative, the parallels are striking. The subject’s childhood experiences and psychological profile exhibit precursors to sadistic, manipulative behavior. Should this suspect indeed be operating under the Jigsaw philosophy, immediate action is required to prevent further fatalities.
