The remains are of 70-year-old Margie Dabney.
Lewisville police Capt. Kevin Deaver said Monday that they were notified Friday of the remains being identified by DNA.
The Tarrant County Medical Examiner's office found that Dabney suffered head trauma and ruled the death a homicide. Police said her remains were found about 15 miles north of the airport.
While the skeletal remains were found a year ago, it wasn't until some of Dabney's personal belongings turned up in an adjacent field in October that police determined the remains might be hers.
The California woman disappeared while she and her husband were changing planes at DFW Airport. They were headed back home to California after visiting Indiana.
