Australian police are assisting their U.S. counterparts on the investigation into Las Vegas shooter's girlfriend Marilou Danley.

The Australian Broadcasting Corporation reports that Philippines-born Danley became an Australian citizen after moving to the Gold Coast in Queensland state and marrying a local man. ABC says she lived there for some 10 years until the late 1980s.

Australian Federal Police Commissioner Andrew Colvin said Friday that as an Australian citizen, Danley was entitled to consular assistance.

Australian police and government officials have not elaborated on Danley's time or citizenship in Australia.

Colvin says the Australian authorities are "working very closely with our partners in the U.S."

Australia's foreign affairs department said Friday it is aware she is "a person of interest" and described her case as "a matter for U.S. law enforcement."

Meanwhile, CBS News has confirmed reports that Stephen Paddock and Marilou Danley visited a car dealership just blocks away from the Atlantis Casino on August 1, 2017. The couple purchased a Hyundai Tucson up front with a check for cash for $14,411.14. 

Employees at the car dealership tell CBS News Marilou was "extremely complimentary" of her boyfriend, adding that he "saved her" from an abusive relationship with her former husband. One employee at the car dealership called Danley kind and caring, an "extremely nice customer."

The car was undoubtedly for Marilou, the employee confirms. Mary Lou test drove the vehicle with a female car dealer. 

The employee called the transaction "innocuous" and "ho-hum" with no red flags, but added he got the impression that Marilou may have been a "bit of a kept woman." 

The employee called Paddock an "educated consumer" who clearly "knew his facts" and "knew what he wanted" from the dealership, adding that he was not going to settle for more than a car's worth.
