Ari Misha Liggett
The man accused of murdering and dismembering his mother pleaded not guilty by reason of insanity on Monday.
CBS4 has learned that for two days this week, police investigators working on the Jessica Ridgeway murder case thought they might have their man. They were heavily focused on Ari Misha Liggett as the likely suspect.
What started as a missing persons case has led to one arrest and the discovery of human remains. A Centennial man has been arrested while deputies investigate whether the remains discovered are those of his mother.
