An Alabama chiropractor who tried to murder his wife by poisoning her with lead he found while his office was under construction has been sentenced to life in prison.

Brian Mann, 36, was found guilty by a jury in June after his wife, 25-year-old Hannah Pettey, testified against him during his trial. Mann was convicted of attempted murder years after he poisoned his wife with lead. Pettey had testified that her estranged husband took out "a lot" of life insurance policies on her at several different companies and discouraged her from seeking medical attention for her symptoms.

At one point, Mann tried to pretend that he and his other children were also suffering from lead poisoning, but became "visibly nervous" when told he would have to be tested.
