Columbia Police Chief Randy Scott told The Associated Press Wednesday that investigators hope Amir Jennings is alive but they aren't getting much help from the boy's mother, Zinah Jennings.
The mother and son were missing for a month before she was found after being in a car accident Christmas Eve. The chief says Jennings told inconsistent stories, saying her son was with friends in North Carolina and Georgia.
Police in both states have found no clues. Jennings has been charged with unlawful conduct toward a child.
Scott says Jennings' mother has told police her daughter's behavior changed after Amir was born.
