Sonia Rivas was 39 when she was last seen in Houston on November 10, 2011. Reports say she walked away from a McDonald’s location that day and has not been seen since. She was described as 5 feet 7 inches tall, about 130 pounds, with gray or partially gray hair.

Her case is listed in NamUs and remains unsolved. Beyond the basic sighting and physical description, little information has been made public about where she went after she left the restaurant or about possible leads developed since then. The Houston community and local law enforcement continue to seek tips that could help bring closure to her family.

If anyone knew Sonia, saw her on November 10, 2011, or has information about her movements that day, please come forward.
