TRANSCRIPT EXCERPT:

[TAPE 1]
Kevin’s Voice (calm, measured):
"I remember the first time they forgot about me. It’s impossible to trust anyone after that. But I learned something about fear—how to wield it. How to use it to teach lessons."

[Pause, slight static]

Kevin’s Voice:
"I was so small… but even a child can build a fortress. It just takes a little ingenuity and a willingness to see others suffer for their mistakes."

[TAPE 2]
Kevin’s Voice:
"You might say I’m twisted, but I call it justice. People only value what they have when it’s threatened. It’s not enough to punish them; they need to learn."

[Long pause, faint background scraping]

Kevin’s Voice:
"I’m… building something. A trial. No more silly pranks. This one… will matter."

[TAPE 4]
Kevin’s Voice (sharp intake of breath):
"They laughed at me for setting traps. They said I was a freak. Soon, they’ll see it’s not about violence—it's about clarity. Pain clarifies. Every day we waste is a chance lost to understand the preciousness of life."

[END EXCERPT]

OFFICIAL NOTE:
These tapes have been entered into evidence under file #CPD-2018-07-KM. The voice has been tentatively matched with one Kevin McAllister (based on known audio samples from old family home videos). Further investigation is pending.
