Core Event: The Poisoning Case of Hannah Pettey
The CBS documentary "The Gaslighting of Hannah Pettey," aired on January 7, 2026, chronicles the harrowing story of Hannah Pettey, who survived a poisoning attempt by her ex-husband, Brian Thomas Mann. Mann was convicted of attempted murder in June 2025 and sentenced to life in prison in August 2025. The case began when Hannah, a mother of two, experienced severe health issues in August 2021 after taking vitamin supplements provided by Mann, who is a chiropractor. By January 2022, she was hospitalized at the University of Alabama at Birmingham (UAB) with severe lead poisoning, which doctors determined could not have occurred accidentally.
Background & Context: Deteriorating Relationship
Hannah and Brian's marriage, which began in 2018, deteriorated amid discussions of divorce in 2021. During this period, Hannah began taking the supplements that Mann claimed would bolster her immune system. However, her health rapidly declined, leading to hospitalization where doctors discovered dangerously high levels of lead in her bloodstream—eight times the normal amount. This alarming diagnosis prompted an investigation into potential foul play.
Investigation and Arrest
Initial investigations considered both Hannah's mother, Nicole Pettey, and Brian as suspects due to their proximity to Hannah. However, evidence soon pointed toward Brian. Authorities discovered five life insurance policies totaling approximately $1.3 million, with Brian as the beneficiary. Suspicion deepened when a contractor revealed that Brian had used lead in the construction of his chiropractic office's X-ray room. Following a tip-off and further investigation, Brian was arrested in September 2022.
Trial and Conviction
Brian Mann's trial commenced in June 2025, where the prosecution presented evidence of his financial motive and the deliberate poisoning of Hannah. Despite his defense claiming he was also a victim of lead poisoning and questioning the evidence's integrity, the jury found him guilty after three hours of deliberation. He was sentenced to life imprisonment without the possibility of parole.
Criticism & Opposition
Critics of the case have pointed to the complexities surrounding domestic violence and the psychological manipulation often involved, as highlighted by Hartselle Police Chief Alan McDearmond. He emphasized that domestic violence can manifest in various forms, including emotional and psychological abuse, as seen in Hannah's experience.
Official Statements & Responses
Following the documentary's release, Chief McDearmond expressed hope that it would encourage current victims of domestic violence to seek help. Hannah herself has shown remarkable resilience, stating, “I’ve forgiven him, and I just wish that he could change someday to change his ways… for his family and children.”
Hannah's Journey: Recovery and Rebuilding
Hannah Pettey's recovery has been a long and challenging process. After enduring extensive medical treatment, including continuous colon irrigation, she has focused on rebuilding her life. She filed for divorce shortly after her hospitalization and graduated with a degree in Elementary Education in December 2024. By 2025, she began teaching second grade, striving to create a stable environment for her children. In September 2025, she and her children moved into a new home, marking a significant step in their healing journey.
