He had married his high-school girlfriend Sharon Yeager in 1960, with whom he had one child, and Jeanne Kirkpatrick in 1973, with whom he had two daughters, Melissa and Jaime, alongside Jeanne's children from a prior union, Christi and Michael.<sup>[2](https://www.thedailybeast.com/the-truth-about-jim-review-was-her-step-grandfather-the-zodiac-killer/)</sup> Sierra had grown up hearing whispers about Jim, but the investigation itself, spurred in part by her own experiences of sexual assault, was what drew detailed accounts out of family members.<sup>[2](https://www.thedailybeast.com/the-truth-about-jim-review-was-her-step-grandfather-the-zodiac-killer/)</sup>\n\n### Episodes\n\nThe four episodes trace the investigation's arc:<sup>[1](https://press.wbd.com/us/media-release/max-original-documentary-series-truth-about-jim-debuts-february-15?language_content_entity=en)</sup><sup> • </sup><sup>[3](https://tv.apple.com/us/show/the-truth-about-jim/umc.cmc.14clxiuhbub3sp6rw00c2w4mt)</sup>\n\n1. **Digging Up the Past** (44 min). Sierra begins investigating her step-grandfather by interviewing Jim's ex-wives, children, and stepchildren, some of whom she had not spoken to in years, assembling a picture of the terror he inflicted on his own family.\n2. **Eight Murdered Girls** (49 min). A family heirloom leads Sierra to a series of unsolved murders, and she questions whether Jim's crimes may have escalated.\n3. **The Devil and Jim Mordecai** (45 min). Sierra's uncle shares a disturbing story implicating Jim, a private investigator urges her to find evidence, and a search through family storage reveals the truth about a night that changed the family, shifting the investigation's direction.\n4. **Out of the Shadows** (50 min). Using modern forensic technology, Sierra builds a DNA profile of Jim and hands her files to law enforcement in the hope of convincing them to investigate.\n\n## The murder allegations\n\nThe series connects Mordecai to the murders of hitchhikers in Santa Rosa in the 1970s, and for a stretch entertains the further theory that he was the [Zodiac Killer](https://www.edgepedia.org/zodiac-killer).<sup>[2](https://www.thedailybeast.com/the-truth-about-jim-review-was-her-step-grandfather-the-zodiac-killer/)</sup><sup> • </sup><sup>[4](https://papiro.unizar.es/ojs/index.php/analisis/es/article/download/11331/9503/42740)</sup> The Zodiac thread is tested within the series itself: after lengthy conversations with Zodiac expert Mike Butterfield that highlight shortcomings in the hypothesis, Sierra accepts that Jim likely was not the Zodiac.<sup>[2](https://www.thedailybeast.com/the-truth-about-jim-review-was-her-step-grandfather-the-zodiac-killer/)</sup>\n\nThe more concrete thread is the DNA effort. Police still hold semen evidence from the Santa Rosa hitchhiking victims, and Sierra's goal is to develop a DNA profile of Jim that police could compare against it.<sup>[2](https://www.thedailybeast.com/the-truth-about-jim-review-was-her-step-grandfather-the-zodiac-killer/)</sup> The series ends without a forensic match or an official identification: closing text cards indicate that Jim's relationship to the Santa Rosa hitchhiking murders remains unknown.<sup>[2](https://www.thedailybeast.com/the-truth-about-jim-review-was-her-step-grandfather-the-zodiac-killer/)</sup> A later analysis of the case distinguishes the two allegations explicitly, noting that the documentary describes material being taken to law enforcement but that this is not an official identification or a demonstrated forensic match, and that evidence or suspicion relevant to the Santa Rosa murders does not by itself establish the Zodiac claim.<sup>[6](https://www.documentarytube.com/blog/was-jim-mordecai-the-zodiac-killer-what-the-evidence-shows/)</sup>\n\n## Reception and interpretation\n\nCritical response was mixed. On Rotten Tomatoes the season held a 47% Tomatometer from four reviews, with fewer than 50 audience ratings; IMDb listed the series at 5.1 out of 10.<sup>[7](https://www.rottentomatoes.com/tv/the_truth_about_jim/s01)</sup><sup> • </sup><sup>[8](https://www.roku.com/en-gb/whats-on/tv-shows/the-truth-about-jim?id=2e63b6d2a21051ec83713434df6497a4)</sup> Nick Schager, reviewing for [The Daily Beast](https://www.edgepedia.org/the-daily-beast), called it an intimate look at women's struggles to have their voices heard while faulting a second half of prolonged detours and few answers to its central questions.<sup>[2](https://www.thedailybeast.com/the-truth-about-jim-review-was-her-step-grandfather-the-zodiac-killer/)</sup> Chris Vognar of Rolling Stone wrote that the series walks alongside Barter competently but never makes the turn into creative subjectivity.<sup>[7](https://www.rottentomatoes.com/tv/the_truth_about_jim/s01)</sup> Alison Lanier of Pajiba praised the story being in the hands of someone actually impacted by it.<sup>[7](https://www.rottentomatoes.com/tv/the_truth_about_jim/s01)</sup>\n\nA scholarly reading of the series emphasizes its first-person perspective: Sierra interviews her mother, grandmother, and other relatives, abuses are narrated in first person, and although the perspectives are subjective, their numerous coincidences give a sense of objectivity. The same analysis notes that the series reaches no conclusion about the murders while leaving a monstrous image of Mordecai, and that the investigative process proves therapeutic for the family by surfacing secrets kept for decades.<sup>[4](https://papiro.unizar.es/ojs/index.php/analisis/es/article/download/11331/9503/42740)</sup> Reviewers likewise observed that the series ultimately refocuses on the therapeutic nature of Sierra's mission, bringing estranged family members together to face harrowing realities, rather than on resolving the title question.<sup>[2](https://www.thedailybeast.com/the-truth-about-jim-review-was-her-step-grandfather-the-zodiac-killer/)</sup>\n\n## Availability\n\nThe series streams on Max and is also available through [HBO Max](https://www.edgepedia.org/hbo-max) via Hulu, Amazon Prime Video, The Roku Channel, and YouTube.<sup>[9](https://www.hulu.com/series/the-truth-about-jim-bbbf9d01-4b06-46d3-8262-a499f680ce89)</sup><sup> • </sup><sup>[10](https://watch.plex.tv/en-GB/show/the-truth-about-jim-1)</sup>\n\n## References\n\n1.
