"But what if there is even a tiny chance he is guilty of abuse? Should such a person be in a position to decide this life-and-death issue?"
Whether or not the Statute of Limitations has run on Michael's possible crime, an investigation is warranted. If Michael is guilty of attempted murder, he has NO RIGHT to make this decision about Terri's life.
Actually Michael already has NO RIGHT to be making these decisions, because of his violations as GUARDIAN.
As her sole guardian, MICHAEL HAS NEGLECTED TERRI FOR YEARS. That right there is enough to trigger a DCF investigation. Now if Hospice was taking orders from HINO all these years instead of from doctors, then they are also in hot water. Major hot water. People in the medical profession are supposed to register complaints of NEGLECT AND ABUSE, NOT PARTICIPATE IN THEM. They are accessories. WHY WON'T DCF GO AND GET HER IMMEDIATELY?
