The state Medical Examiner's Office says the human remains found in a dumpster in Okmulgee were those of a missing 25-year-old Colorado woman.
Ashley Mead of Boulder was reported missing in February along with her 1-year-old daughter. The girl was found with her father, Adam Densmore west of Tulsa.
Mead's torso was found in a suitcase in a trash container next service station at a Okmulgee Walmart.
The Oklahoma Office of the Chief Medical Examiner confirmed that the remains were Mead's.
Densmore is charged with first-degree murder and tampering. He has not entered a plea. Investigators believe Mead was killed in Boulder and dismembered in Louisiana, but searchers have been unable to find the rest of her remains.
Adam Densmore remains in a Colorado jail without bond with a May 4 preliminary hearing set.
