So it's a recent investigation, which, of course, begs the question why there wasn't one before.
There was one before but Judge Greer had it sealed. I don't know the date of that investigation. Someone else might know.
1.) Have you not heard about how many problems the DCF has been having for the last ten or so years? They just realized a few weeks ago that there was all kinds of stuff that never got investigated. I think they are trying to right a few wrongs before they have more egg on their face.
2.) Apparently, the agency that last looked into these allegations didn't get to take a look at Terri, because Michael refused them access. Obviously they didn't have much pull if the guardian could tell them to take a hike. Also, I understand that once Terri's law came in to effect, they just stopped with their investigation altogether.
