DENVER — A judge sentenced Ari Liggett to life in prison Friday, four days after he was found guilty of first-degree murder for poisoning and dismembering his mother in 2012.

“The only place for Liggett is prison. His family believes strongly that they would be in grave danger if he were ever free,” said prosecutor Brian Sugioka at the sentencing hearing.

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.

“What was striking to the court was the fact that this particular case is nothing short of a tragedy,” said Judge Michelle Amico. “There are no winners in this case. We got a glimpse into the lives of this family. It was nothing short of climbing a mountain.”

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.
