Son, 24, found and arrested after woman's body parts discovered in his car just days after he and his mom were reported missing

What started out as a missing person's case has turned into a murder investigation after the dismembered body of a woman was found in the backseat of a car.
Ari Misha Liggett, 24, of Centennial, Denver, was arrested two days after he and his 56-year-old mother were reported missing by concerned family members.
Though the remains have not yet been identified, mother Beverly Liggett is still missing.

Ari Misha Liggett, a 24-year-old man who was reported missing along with his mother on Monday was arrested on Wednesday for first-degree murder

Police were asked to perform a welfare check on the Liggett home on Monday in the 6200 block of East Peakview Drive, where they found poison

Family called police to perform a welfare check on the home on Monday evening.
There was no one at home but police were able to verify their whereabouts after tracing credit card transactions.


The car was then apprehended on Wednesday and the 24-year-old was arrested after a police chase which resulted in Liggett crashing the car.
He fled the scene on foot but was captured a short time later, according to the Denver Post.
Liggett is being held without bond in the Arapahoe County Sheriff's Office Detention Facility on suspicion of first-degree murder.

Liggett was arrested in 2010 and pleaded guilty to reckless endangerment, receiving a four-year deferred sentence and one year of probation

When police searched the home, they found potassium cyanide which is one of the most fast-acting poisons known.
In 2010, Liggett was also arrested and accused of smuggling an unknown substance into a homeless shelter which caused it to be evacuated for seven hours.
The chemical was not able to be identified and he was not charged with a hazardous-material violation. 
He was, however, charged with possession of a dangerous weapon after he was found with a silencer a shirt time later.
