Centennial man convicted of poisoning, dismembering mom in will dispute
CENTENNIAL, Colo. — An Arapahoe County jury returned a guilty verdict in the case of Ari Liggett, who was accused of poisoning and dismembering his mother in 2012 after she cut him out of her will.
Liggett had pleaded not guilty by reason of mental insanity, with his lawyers arguing he suffered from a mental health disease that had never been properly diagnosed. Public defenders for Liggett presented evidence that he was diagnosed with a developmental disorder at the age of 5, and had been hospitalized five times due to issues with mental health.
However, prosecutors counter by presented evidence that Liggett had been buying chemicals and practicing poisonous mixtures for years before murdering his 56-year-old mother, Beverly, the woman he blamed for many of his mental health issues, in their Centennial home.
Ultimately, jurors found the 26-year-old guilty of first degree murder after deliberation Monday after closing arguments were presented on Friday of last week. A sentencing hearing was then set for this coming Friday, at which point in time Liggett is expected to be sentenced to life in prison.
Liggett was arrested in October 2012, after a chase with police that ended with him crashing his mother’s SUV. His mother’s remains where found in storage bins in the back of the vehicle.
“Bev was a very smart person, very lovely and very warm and giving woman,” said Seth Masiz, Beverley’s fiance at the time of her death. “She spent her whole life looking after other people; as a special education teacher and then as a registered nurse. She spent her whole life looking after Ari, and she didn’t deserve this.”
