Carter said she does not know who is operating the page on Johnson's behalf but that the Department of Correction couldn't do anything about it even if they did, saying that the page is "out of their hands."
"For victims and victims' families, especially, we really want them to know that the Department of Correction isn't allowing this sort of stuff to happen inside the prisons and if we could control it, we would," said Carter.
"We're always concerned if the public is concerned about what's happening inside the institution and when it spills out in the community and if victims are concerned, we want to address it the best we can," said Carter.
Carter added she was not sure what kind of monitoring, if any, would take the place of Johnson's page, but urged any victims or victims' families who receive unsolicited communication from prisoners to notify authorities.
Johnson's mother, Kathy Bunche, did not respond to messages sent to her by ABCNews.com, but told ABC News affiliate KMBC that she thinks her son's popularity on Facebook indicates his innocence.
"A lot of people love him, you can see that," said Bunche. "They understand that the story he is a monster can't be right. Everybody knows that's not the case."
