As the search for a missing 12-year-old Arizona girl entered its second week, the child's mother spoke out, saying, "I'm scared to death."

       Betty Taylor was reported missing by her family eight days ago after she told her father was going for a walk and never returned to her home in Safford, Arizona, according to the Graham County Sheriff's Office.

       Over the weekend, community volunteers fanned out across the Graham County town, passing out missing person flyers to raise awareness about the child's disappearance.

       Police have also used helicopters, search dogs and drones to look for the girl, and officers on horseback and all-terrain vehicles have combed the desert area around the small town at the foot of the Pinaleno Mountains in southeast Arizona, about 130 miles from Tucson.

       "I'm scared to death about what she's going through. I don't know if she's out there on her own. I don't know if she has a safe place to be. I don't know if she's eating," the girl's anguished mother, Bonnie Jones, told ABC affiliate station KNXV in Phoenix.

       Betty was last seen on March 20 when she left her home at about 11 a.m., telling her father, Justin Taylor, she was going for a walk, according to a statement from the Graham County Sheriff's Office. When she failed to return home by 6 p.m. that day, the family went searching for her before reporting her missing at 8 p.m. that night, according to the statement.
