Mom investigated for human trafficking after 'funny' tweet

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.
