Rosemary Gonzalez was 16 and living in Huntington Park, California, when she was last seen on February 20, 2010. Her foster family reported her missing after she stopped making contact. She had a one-year-old son, Mervin Diaz-Gonzalez, who was also reported missing about the same time.

Rosemary is described as 5 feet 2 inches, about 120 pounds, with brown hair and brown eyes. On the day she disappeared she was reportedly wearing black jeans, a brown shirt and a gold necklace. There was a belief she may have traveled to Missouri, and unconfirmed speculation the child may have been taken to Guatemala, but neither contact nor confirmation followed.

Very little is known about what led to their disappearance and both cases remain unsolved. Anyone who knew Rosemary, her son, their movements before February 20, 2010, or who has information about their possible travel is asked to come forward.
