Questions on the Gage Murder

I understand from the article in today's Register that Trena Gage is claiming she didn't know Roger Bentley was a sex offender. But presuming that's true: 1) Wouldn't it be common sense to limit contact with the family anyway, considering both Trena and Jetseta were scheduled to testify against James Bentley and potentially put him in prison? 2) Where was DHS and couldn't they insist on limiting the contact if Trena wouldn't? They had the information on Roger Bentley. They should have been involved based on the molestation by James Bentley. Was there not sufficient basis for a CHiNA removal here? Dweeze has the same questions, as does Not the Moonbat. >
