Notable Cases of Serial Killers Linked to St. Louis
Larry DeWayne Hall

He was apprehended outside Missouri, leading to extradition and a life sentence. Case file details include victim age ranges, forensic evidence recovery, and interstate cooperation. This case illustrates cross-jurisdictional challenges in prosecuting mobile serial offenders.
Jerome Dennis
Jerome Dennis was convicted of multiple murders in the St. Louis area spanning the late 1980s into the early 1990s. His pattern involved acquaintance victims, often with prior criminal records, leveraging access and trust. Law enforcement connected several unsolved disappearances to his activities through witness accounts and circumstantial evidence. Sentencing resulted in long-term incarceration, though appeals have periodically revisited procedural claims. This case highlights how serial investigations rely on cumulative evidence rather than isolated incidents.
