Martha Jimenez, 44, was last seen on April 9, 2011, in Conroe, Texas, while working the night shift at a small convenience store on Old Magnolia Road. Surveillance footage shows her locking up the store around midnight; that is the last confirmed sighting. She was reported missing the next day by her 18-year-old daughter after Martha did not return home.

In the weeks after her disappearance, the Conroe Police Department and volunteer teams, including Texas EquuSearch, carried out extensive searches that included a landfill in Montgomery County, but no substantial leads turned up. There were no immediate signs of foul play at the store. The case remains unsolved and the department asks anyone with information to come forward.

If anyone knew Martha’s routines, work schedule, or saw her the night of April 9, please share what you know with investigators.
