(CBS) CENTENNIAL, Colo.- Ari Misha Liggett was arrested early Wednesday morning after police say they found the dismembered remains of an unidentified adult female in the back of his car, CBS Denver reports.
Arapahoe County Sheriff's deputies are investigating whether or not the remains are the 24-year-old's missing mother, whose name has not been released.
Family members became concerned for the welfare of the woman and her son and reported them both missing on Monday. Deputies began an investigation, tracking the pair through credit card transactions.
Around 1:30 a.m. on Wednesday, deputies watched a vehicle associated with Liggett and his mother being driven through the neighborhood close to their home but were unable to make contact. Twenty minutes later, Greenwood Village Police Department attempted to conduct a traffic stop on the car, but Liggett eluded police and crashed his car. Ligget fled on foot and was soon apprehended by an officer.
The dismembered remains of an adult female were found in the back seat of the vehicle he was driving. The remains have yet to be identified and Liggett's mother is still missing.
Liggett remains in custody at the Arapahoe County Sheriff's Office Detention Facility without bond pending the filing of first degree murder charges.
The investigation continued at Liggett's home where suspicious liquid was discovered by hazardous materials crews. The liquid is being tested at two different facilities. The area around the home was closed off for several hours on Tuesday evening while the liquid was being removed from the house.
Deputies said the liquid has been contained and is not a threat to surrounding homes.
