A Mississippi mom's tweet about her son landed her in a human trafficking investigation.
Alex McDaniel posted a message on Twitter saying her 3-year-old son was for sale for $12 or best offer.
She says she meant the tweet as a joke, but someone saw it and reported it to a child abuse hotline.
McDaniel says a CPS worker dropped by her office and demanded to see the child.
The investigation was eventually dropped.
McDaniel says she wants her story to be used as a warning to be careful about what you post online.
