Michael Lutts, from California, pleaded guilty recently of sexual exploitation of a child and distribution of child pornography. According to NBC San Diego, “he admitted to 15 instances of photographing or videotaping the infants in sexually explicit situations at both his home and his workplace.”

Having been investigated in August of 2014, he was let go from his job as a pediatric nurse with Kaiser Permanente in September of the same year. Two other men have been accused of conspiring with Lutts, directing him to abuse and send pictures.

The FBI investigation into Lutts came from a search warrant on an email address from which child pornography was being distributed. When his home was searched, hundreds of child pornography images were found on his computers.
