ALBUQUERQUE, N.M. (AP) — Authorities believe a woman whose body was found on a New Mexico mesa this month left behind a cellphone video of herself.

KOAT-TV reports (http://bit.ly/1pK7MgX) Sandoval County Sheriff Doug Wood said Monday the video shows the woman talking about how she had been lost for two days.

Authorities believe the remains might belong to Brenda Salas, a 27-year-old who disappeared in June 2012. A family found the remains Sunday while fossil hunting on the West Mesa, a desert area near Albuquerque.

The video has not been released.

Authorities say DNA tests and dental records could take anywhere from a couple of weeks to two months. Wood says investigators will show the family the message after they're processed the video and other evidence related to the cellphone.

The medical examiner is investigating the cause of death.
