A Dallas mother is accused of trying to sell her 4-month-old boy online. Britany Hill, 26, was arrested Friday and charged with child abandonment. 

Police were notified of the online posting by a Florida woman who thought about adopting the child, but changed her mind and called authorities.

The baby was found alone inside Hill's apartment on Friday and placed in the care of Child Protective Services.

Police said Hill was selling the baby for $4,000. They have not said if she would be charged with posting the online ad.
