Dismembered body found in car after chase; Centennial man arrested

Grown son, mother reported missing on Monday

CENTENNIAL, Colo. - The son of a missing Centennial woman faces first-degree murder charges after a dismembered body was found in the back seat of a car, officials said Wednesday.

Family members reported on Monday that a 56-year-old woman and her 24-year-old son were missing and the family was concerned for their welfare.  The mother and son reside together at an East Peakview Avenue address.

Investigators checking credit card transactions determined the two had traveled to the Western Slope on Tuesday.

Early Wednesday, sheriff's deputies observed the car associated with the missing persons report traveling through a Centennial neighborhood but were unable to stop it.  A short time later, a Greenwood Village police officer attempted to stop the vehicle and a chase ensued.

The car crashed and the driver jumped out of the car and ran but the Arapahoe County Sheriff's Office said the driver was apprehended a short time later.  Investigators said they found the dismembered remains of an adult female in the back seat of the crashed automobile.

The sheriff's office said Ari Misha Liggett, 24, was booked into the Arapahoe County Jail for investigation of first-degree murder.   Liggett was identified as the missing son investigators were looking for.

The body is yet to be positively identified, pending further investigation by the Arapahoe County Coroner's Office.

While conducting the initial search of the home at 6223 East Peakview Ave., investigators discovered a suspicious liquid inside the home.  Preliminary testing determined that the suspicious liquid appeared to be potassium cyanide.

In March 2010, Liggett was arrested at a Boulder homeless shelter during a hazmat incident.

The shelter was evacuated after Liggett told police he was storing hazardous chemicals there.

Liggett was arrested on an unrelated weapons charge.

7NEWS asked Arapahoe County Sheriff Grayson Robinson about a possible link to the Jessica Ridgeway case.

"We have discussed the situation with various entities and do not believe there is a link at this time," he said.
