COCHISE COUNTY, Ariz. (KGUN) — The Cochise County Sheriff's Office is investigating a heinous double murder after a man and woman were reported missing in September. Investigators tell KGUN 9 the suspect tried to bury a car to hide evidence.

Cochise County has identified the two who were murdered and buried as Gregory Carlson's ex-wife Duong Nguyen and her friend Robert Atwell.

A Cochise County spokesperson says Nguyen flew from Pennsylvania with Atwell. The two went to Carlson's home to pick up the couple's young daughter on Sep. 3, before being reported missing on Sep. 4.

Deputies responded to Carlson's home on the 7000 block of Aschenbach Road, near Pearce, Arizona.

Investigators searched the property with a warrant and found two bodies burned in a pit. A second pit was also discovered, which had been dug to hide Nguyen's rental car.

Now, 56-year-old Gregory Carlson is facing two charges of first-degree murder-premeditated, two charges of second-degree murder, as well as concealment of bodies and tampering with evidence.

Carlson remains in custody and has a hearing in February.

The daughter is now with Nguyen's side of the family.
