The episode begins with an introduction to the Zodiac Killer, a serial killer who terrorized Northern California in the late 1960s and early 1970s. The hosts highlight the case's enduring fascination due to its brutality and the unsolved mystery of the killer's identity. Dr. Hewitt, author of several books on the Zodiac Killer, including his latest work, "Obsessed: My Relentless Pursuit of the Zodiac Killer," shares his motivation for writing the memoir and the extensive research that went into his Zodiac trilogy. He provides a detailed account of the Zodiac Killer's known attacks and murders, starting with the Lake Herman Road case in 1968. Hewitt highlights the progression of the killer's MO, from drive-by shootings to a more hands-on approach involving a bayonet-style knife. The episode delves into the Zodiac's shifting modus operandi, particularly the transition from drive-by shootings to a more personal and violent attack at Lake Berryessa. The hosts and Hewitt speculate on the reasons behind this change, including a possible desire for greater control and a shift in the killer's personality. Hewitt discusses the Zodiac's apparent disappearance after the Presidio Heights murder in 1970, exploring the possibility that the killer was motivated by a desire for notoriety and that the San Francisco attack was a calculated attempt to increase media attention. The episode also explores the Zodiac's motives, particularly the choice of Paul Stein, a solo male cab driver, as his final victim. They consider the possibility that the killer was seeking to prove his dominance after surviving victims in previous attacks. Hewitt explains the Zodiac's use of ciphers and the "radiant angle" theory, which suggests that the killer strategically planned his attacks to form a specific geometric pattern. He acknowledges the debate surrounding the theory and its validity. The episode also discusses the Zodiac's phone calls to police and news outlets, highlighting their unusual nature and the risk the killer took by making them. Hewitt explores the possibility that the calls were motivated by a desire for attention and a need to boast about his crimes. The episode delves into the Zodiac's communication style, noting his unemotional and boastful tone in phone calls and letters. Hewitt suggests that the killer's need for recognition and control was a driving force behind his actions. The hosts and Hewitt discuss the possibility that the Zodiac was trying to convey a message to society through his crimes and communications. They explore the meaning behind his references to "slaves for the afterlife" and his overall desire to outsmart law enforcement. Hewitt highlights the Zodiac's near capture in the Presidio Heights case, emphasizing the role of luck and miscommunication in his escape. He suggests that this close call may have deterred the killer from engaging in further close-up attacks. The episode also discusses the Zodiac's claim to wear disguises, particularly in light of the Lake Berryessa attack. They explore the possibility that the killer was using this claim to sow doubt and undermine eyewitness accounts. Hewitt discusses the challenges of identifying the Zodiac, highlighting the limitations of eyewitness accounts and the difficulty of relying on circulated photos. He emphasizes the need for more reliable evidence to solve the case. The episode explores the potential of forensic linguistics to shed light on the Zodiac's identity, explaining how language patterns can reveal insights into a person's background, experiences, and even their psychological state. Hewitt acknowledges the challenges of using forensic linguistics on the Zodiac case due to the killer's apparent attempts to manipulate his language and intelligence level. He suggests that advancements in AI and supercomputers may offer new avenues for analysis. The episode discusses the Zodiac's letters as a form of staging, highlighting the possibility that they were intended to mislead investigators rather than reveal information about the killer. The hosts and Hewitt discuss the Zodiac's contradictory language use, noting his ability to use semicolons while misspelling basic words. They explore the possibility that the killer was intentionally manipulating his language to create a false impression of his intelligence. Hewitt discusses the Zodiac's use of misdirection in his communications, suggesting that he may have intentionally included false information to mislead investigators. He attributes the enduring fascination with the case to the abundance of information and the multiple interpretations it allows. Hewitt argues that the Zodiac's true identity may never be revealed because investigators have become fixated on a fabricated persona created by the killer through his letters. He suggests that the killer's true self may be vastly different from the image he projected. Hewitt discusses his approach to creating a criminal profile of the Zodiac in his book "Profile of the Zodiac Examined." He highlights the use of FBI research and forensic evidence to narrow down the potential characteristics of the killer. Hewitt debunks the Hollywood stereotype of serial killers as large, menacing figures. He emphasizes that serial killers often blend into society and appear ordinary, making them difficult to identify. Hewitt presents his psychological profile of the Zodiac, suggesting that he was likely a firstborn or only child, around 30 years old, and exhibiting signs of rage, alienation, and relationship problems. The hosts and Hewitt discuss the Zodiac's motivation, suggesting that he was driven by a desire to destroy what he could not have or be. They highlight his loner personality and his need for control. Hewitt discusses the Zodiac's potential post-offense behavior, suggesting that his organized nature and desire to avoid capture may have led him to use alcohol as a coping mechanism. The hosts and Hewitt discuss the Zodiac's terrorist nature, highlighting his deliberate efforts to terrorize communities and instill fear in the population. They emphasize the importance of recognizing this aspect of his crimes. Hewitt discusses the lasting impact of the Zodiac's crimes, noting that many people still carry vivid memories of the fear and uncertainty he created.
