A Philadelphia mother has been charged in the death of her 4-year-old child but no body has been found, authorities said. 

The Philadelphia Police Department's Special Victims Unit opened an investigation into a missing child on Dec. 30, despite the mother not making the claim, the Philadelphia Police Department told Fox News Digital. 

Dominique Bailey, 28, allegedly told her family that the child was hit and killed by a vehicle. Investigators didn't find any evidence to support the claim, the news report said.
