Mitchell County Sheriff Patrick Toombs learned about the photos about two weeks ago. He called them examples of "unusual or strange behavior."
Law enforcement is not looking into the photos as part of the criminal investigation into the disappearance of Billie Dunn's 13 year old daughter, Hailey. Toombs says it's unclear when they were taken, but he says he's heard they may have been taken after Hailey disappeared in late December 2010.
Volunteer searchers say they're focused on finding Hailey, rather than the personal life of the girl's mother.
"We're just still trying to keep everything geared towards Hailey and bringing her home versus what the parents are doing," said searcher Kristy Lloyd.
Sheriff Toombs couldn't definitively say whether Billie Dunn is a person of interest in her daughter's disappearance.
"There [are] just some strange things that have gone on, so that's why she's not been ruled out, but she's not also being named a suspect in the case either," Toombs said.
