Marlana Marie McElvaine was 27 when she was last seen in Tucson on the evening of September 12, 2010. A mother of two small children, then four months and two and a half years old, she had been living with her boyfriend. Friends and family described her as a devoted mother who had plans to attend nursing school and would not have willingly abandoned her children.

Several days after she disappeared, her car was found abandoned in a remote area near South Cardinal Avenue and West Valencia Road with the keys reportedly still in the ignition and her work identification inside. Those details prompted homicide detectives to become involved and the Tucson Police Department now classifies the case as a long-term missing persons case and a cold case homicide, though no charges have been filed. The family says there was a history of domestic abuse in her relationship and her mother has continued to press for answers.

If anyone in the Tucson area remembers Marlana, her car, or unusual activity around South Cardinal Avenue and West Valencia Road in mid-September 2010, can you share what you know?
