County coroner's records match the date of birth, name and hometown of Tasha Thomas who was on the phone with John Crawford the night of Aug. 5 when he was shot and killed inside the store.
Autopsies will be performed Friday on Thomas and Bailey, a coroner's official said.
Both were ejected from a speeding gray Pontiac after it crashed about 3 p.m., said Cara Neace, a spokeswoman for the Dayton police department.
They were not wearing seatbelts.
It is not clear who was driving, but police estimated on scene the vehicle may have been going 90 mph or faster. Alcohol also may have been a factor, Neace said.
Thomas was pronounced dead at the scene.
Bailey was taken to Miami Valley Hospital, where he later died.
Crawford was killed inside the store while holding an air-pellet rifle he picked up from a shelf.
A 911 caller told police the replica gun was a real one, and police have said Crawford did not obey commands to drop the weapon.
A grand jury has declined to indict the officers involved. The U.S. Department of Justice is reportedly conducting a separate review of Beavercreek police's actions.

Last month, the Ohio Attorney General's Office released video footage from an interview police did with Thomas after the shooting. It shows a detective threatening Thomas with a lie detector test and ask if she's on drugs.
