Mary Rhodes Robertson, 61, was last seen at her Lake City, Florida, home on the morning of May 6, 2015. She suffered from dementia and needed daily medication, which she did not have when she left on foot around 10 a.m. after her husband last saw her. She did not have access to a vehicle.

She had wandered before but was usually found nearby. This time, extensive searches by multiple agencies — including bloodhounds, aircraft, ATVs, and volunteers canvassing neighborhoods and wooded areas — lasted several days and produced no sign of her. Occasional tips and reported sightings have not led to her being found. The Columbia County Sheriff’s Office continues to investigate and is asking for information that could help bring closure to her family.

If anyone has information about Mary’s movements on or after May 6, 2015, or remembers seeing her in the Lake City area that day, please contact the Columbia County Sheriff’s Office.
