A one-year-old boy was found wandering alone, after his mother seems to have vanished. Nicole Smith was last seen Sunday, and her family says it's very unlike her to just leave her son alone.

"I don't think she would walk away from her baby, that's not Nicole,” Smith's older sister, Melanie Hunt, tells WXYZ.

Police and Nicole's family believe the 33-year old is being held against her will. Anyone with information is asked to call Detroit police, or 1-800-SPEAK-UP.
