Check his computer.
The perp says he molested family members, apparently 20 years ago. No one so far has come out to verify that they were molested. I believe that a toddler could forget being molested, so it is possible that no one will be able to verify this. That being said it is an excellent idea to check his computer if he had one.
Sadly, I was most likely right that he is a child molester and this was what he had planned for those girls.
