Authorities in Florida are investigating an advertisement on Craigslist offering the sale of a baby for $500.

A Florida Department of Law Enforcement spokesperson, Gertl Plessinger told the Miami Herald that authorities have opened an investigation but declined to go into details about the case.

"I work for department of children and families. I don't wanna be judged for not wanting these kids."
