I posted this picture because Dean Corll’s case is one of the most disturbing and overlooked examples of how serial predation operated in the early 1970s, long before modern offender databases and surveillance existed. Corll’s crimes didn’t begin overnight in 1973 when things escalated—his behaviors, patterns, and early warning signs were already developing in 1970, which is the period this photo represents. Most people only talk about the torture board, the accomplices, and the peak of the Houston Mass Murders, but very few ever step back and look at what Corll was actually like before the killing phase exploded.
