Olga Florinda Mora Lopez, 39, was last seen on July 23, 2011, near Lukeville on the U.S.-Mexico border in Pima County. She was traveling with her sister and, according to the sister’s account, was left just outside of Arivaca near Highway 19 in an area possibly called La Planada after becoming too exhausted to continue walking. She was not reported injured when last seen.

At that time Olga was described as a Hispanic female with brown hair and brown eyes. She wore dark blue jeans, a brown short-sleeved shirt, a navy-blue sweater, gray socks, light blue tennis shoes, and a light blue hat with the letters SD. She had two earrings in each ear and two birthmarks, one on each side of her nose. The Pima County Medical Examiner’s Office opened a case for her on August 10, 2011, and the case remains open.

If anyone was in the Lukeville–Arivaca area on July 23, 2011, or remembers seeing a woman matching Olga’s description, please come forward with information.
