Una Mae Herd, 81, was last seen the morning of June 25, 2006, in Sherman, Texas. She left her home on North Harrison Avenue for her routine morning walk and was seen near Old Settlers Park, about five blocks from her house. She was due to meet her great-granddaughter for breakfast later that morning — a ten-year tradition — but never arrived.

Her home showed no obvious signs of disturbance: her purse, a coffee cup, and the newspaper were on the kitchen table and her car was parked in the garage. Herd had high blood pressure and diabetes but did not have Alzheimer’s or dementia. Authorities and the community conducted extensive searches, foul play is suspected, and the case remains unsolved and cold.

If anyone saw Una around Old Settlers Park or on North Harrison Avenue the morning of June 25, 2006, or remembers anything that could help, please share what you know.
