Please make sure you get that right. They did not live with Michael, he lived with them, and for a few months, they all took care of Terri together. When Michael moved out, it was because he was moving in with another romantic interest (not Jodi, this was around the time of the malpractice trial). He had Terri's two cats euthanized because his girlfriend had a dog, and didn't want to add the cats to the mix. As it turned out, Michael ended up not moving in with this woman, on the advice of his lawyer, because it wouldn't look good at the malpractice trial.
Also understand that Mr. Schindler didn't have doubts about Michael until after the malpractice trial jury had awarded money for Terri's rehab. That's when it started to sink in what he was up against. You mentioned that there "were several stories true or false about the Shiendlers that were never asked of them". I can only say that the same has gone on for Michael.
