For starters, Terri survived her initial collapse. It got removed from homicide because she pulled through. Secondly, Michael's future MIL worked for Sheriff Rice's office before she passed away last September (2004).
Thirdly, and most horrible, is that there actually WAS an investigation by the DCF, but the contents of its findings were sealed by the court (Greer), because it had been quashed by someone at the DCF. Mitch Turner was one of the investigators. I have no idea how to get that file opened, but I can tell you, this is just one horrible thing after another. It's a little hard to understand why so many are so desperate to suppress the truth about Terri's true status.
The truth here is as obvious as a billboard.
What is MIL?
Thank you. That explains a lot.
The police probably botched the job, and/or are hiding cover-up by someone & perhaps that's why they are so desperate to suppress evidence.
How could Michael have a future mother-in-law if he did not and could not marry again (he did not divorce Terri)?
Why? Lots and lots of MONEY.
