The Long Island Serial Killer: The Rex Heuermann Case Update

Rex Heuermann has been charged with two additional murders, specifically those of Sandra Costilla and Jessica Taylor, after advanced DNA testing linked him and his former wife to hairs found at the crime scenes. Investigators also discovered a meticulous "planning document" on a deleted file that served as a blueprint for his crimes, detailing necessary tools, body disposal sites, and methods to avoid leaving evidence like DNA or fingerprints. This document included disturbing self-reminders to improve his killing techniques, control noise to avoid detection, and even references to professional criminal profiling literature to refine his lethal process.
