Earle Leonard Nelson, AKA The Gorilla Man Killer Earle Leonard Nelson, dubbed "The Gorilla Man" and "The Dark Strangler" by the press, was a serial killer who preyed on women across North America in the 1920s. The document, told from the perspective of journalist Thomas McKenna, chronicles Nelson's two-year killing spree, his eventual capture in Canada, and the subsequent trial and execution. Nelson, a man with a traumatic brain injury and a history of mental illness, utilized a charming and polite persona to gain the trust of his victims, who were primarily boarding house operators. His crimes, characterized by manual strangulation and the careful arrangement of his victims' bodies, escalated in violence and frequency as he traveled from California to the Canadian prairies. The case exposed the primitive state of 1920s police technology and communication, which Nelson expertly exploited to evade capture for months. It also highlighted the sensationalism of "Jazz Journalism," which sensationalized his crimes and turned Nelson into a morbid celebrity. The trial and execution raised complex questions about criminal responsibility and the intersection of mental illness and justice. His legacy is not only his horrific crimes but also the lasting impact he had on forensics, criminal profiling, and media's role in a national manhunt.
