Sonia Rodriguez was 37 when she was last seen in South Gate, California, on December 4, 2011. She told a reporting party she was going to visit a friend in Rosemead that day; shortly afterward attempts to reach her went straight to voicemail and she has not been heard from since.

At the time she disappeared Sonia was described as 5 feet 4 inches tall, about 158 pounds, with black hair. Investigators and family report that efforts to trace her whereabouts have produced little information and the case remains unresolved.

Did anyone in South Gate or Rosemead see Sonia around December 4, 2011, or have information that could help clarify what happened?
