by Huntsville, Alabama – A shocking case of betrayal and attempted murder came to a close this week when an Alabama chiropractor was sentenced to life in prison for deliberately poisoning his wife with lead-tainted vitamins during a bitter divorce battle.
Brian Thomas Mann, 36, was found guilty of attempted murder after a jury determined he secretly laced his wife’s daily vitamins with dangerous amounts of lead. Prosecutors revealed that Mann’s scheme lasted for months, leaving his wife, 26-year-old Hannah Pettey, hospitalized and fighting for her life.
The Poisoning Plot
Mann and Pettey had been going through a heated divorce in 2021 when Pettey began taking vitamins to strengthen her immune system. What she didn’t know was that her husband had mixed in toxic lead particles that he stockpiled from leftover construction material at his chiropractic office.
According to testimony, a contractor had installed lead-lined walls for an X-ray room in Mann’s office remodel. Some of the leftover lead was later found to have been used in the vitamins Mann prepared for his wife.
As Pettey’s health deteriorated, doctors discovered she had eight times the normal level of lead in her body. She required two months of hospitalization and intensive treatment, including procedures to drain her colon.
Though she survived, Pettey lost over 40 pounds and continues to live with the long-term effects of lead exposure.
Suspicious Behavior and Life Insurance Motive
Authorities began investigating after medical professionals raised suspicions about Pettey’s unusual illness. Evidence presented in court showed that Mann repeatedly pressured his wife to purchase more life insurance policies, raising questions about his financial motives.
Had Pettey died, Mann stood to collect $1 million in life insurance payouts.
According to NY Post, During the investigation, Mann initially cooperated with police, even handing over the vitamins he gave Pettey. But prosecutors said he later tried to mislead medical staff, claiming he himself had ingested lead. A hospital nurse testified that Mann became visibly nervous when asked to undergo another scan, which revealed only trace amounts of lead in his system.
Anonymous Tip Leads to Breakthrough
The case took a decisive turn when an anonymous tipster contacted police, revealing Mann’s office remodel and confirming that leftover lead had been given to him. That information linked directly to the source of the poison found in Pettey’s body.
In September 2022, Mann was arrested and charged with attempted murder. His trial ended in a guilty verdict earlier this year, and prosecutors pushed for the maximum penalty.

Judge Imposes Maximum Sentence
On Wednesday, the judge sentenced Mann to life in prison, siding with state prosecutors who argued that his actions showed a callous disregard for human life.
Lead prosecutor Garrick Vickery described Mann’s actions as calculated and cold:
“I believe this was a good glimpse into Brian Mann’s character. I don’t know if he took this seriously or if he takes anything seriously outside of himself and his pursuit of money. It’s a peek into his soul.”
Victim’s Recovery and Ongoing Struggles
While Pettey survived the ordeal, doctors testified that she still suffers from the lingering impact of lead poisoning, which can cause neurological damage, organ failure, and chronic health complications.
Her survival is considered fortunate, as lead ingestion in such amounts is often fatal. The court acknowledged her strength and determination in surviving such a traumatic event.
A Case That Shocked Alabama
The case has drawn national attention due to its disturbing details: a trusted spouse turning into a silent killer. The court emphasized that Mann’s method of poisoning highlighted premeditation and cruelty, as the effects of lead poisoning are slow, painful, and devastating.
For many in Huntsville and across Alabama, the story is a chilling reminder of how greed and bitterness can push a person to extremes.
Final Thoughts
Cases like this underscore the importance of vigilant medical care and thorough investigations. Without the persistence of doctors, nurses, and investigators, Mann’s crime may never have been uncovered.
As Pettey continues her recovery, her story stands as a testament to resilience, even in the face of betrayal by the person she once trusted most.
