Since all else has failed to this point. Why doesn't her family file charges against the husband for attempted murder, for having caused her initial injury since they have found the x-rays with damage to her neck.
They could then demand that this removal of life sustaining food and water be reversed because Teri is the only witness to what has happened. In the mean time file a motion to get his guardianship removed and this whole thing moved to another court since Judge Greer is intent upon killing Teri - again the only witness. Get the new court to order rehabilitative therapy so that she might in someway be able to testify against her husband at the trial.
Seems to me that with his failure to provide rehabilition, basic care and his own statements and actions witnessed by any number of other people they have a case against him. Others have been found guilty for far less than what they seem to have on Michael Schiavo.
Is anyone in contact with Teri's family or their attorney? I know this sounds desperate, but desperate times warrant desperate measures.
