Danny Platt didn't like the idea of actually having to support the child he helped bring into this world. And, although many men feel themselves having the same annoyance that "OMG they actually are expected to pay child support for their own offspring", Platt's irritation at the idea went past the normal reaction. Police say that after he had the child for visitation, a right he'd had but repeatedly shunned, he alerted police that men with AK-47's had kidnapped the child. While his story started filling up with more holes than Spongebob- Platt decided to confess the truth to LE.
Riley said Platt eventually confessed and told officers where to find the body.At some point, Platt had openly said he'd either kill his former wife or the child, in an effort to avoid having to pay support, although there are no details to when the comment was made. Police are not releasing cause of death, or injuries the child may have received while in Platt's custody. SOURCE.
