Why Does the Trinity Killer Kill
In the series, the Trinity Killer targets families during specific holidays, following a rigid pattern tied to his traumatic childhood. His motive is rooted in a warped sense of ritual and control, not financial gain or revenge against a specific person.
Real Case Parallels and Impact
