"The Hospice supervisor notified Mrs. Schiavo's husband, Michael, who called his attorney and his wife's physician, Dr. Stanton Tripodis. The physician examined Mrs. Schiavo at Park Place, and authorized her transfer to Mease Hospital in Dunedin for an examination."
Various procedures, including toxicology tests for the presence of unauthorized drugs, proved negative, and Mrs. Schiavo was returned to Hospice care.
Police Report
If you want to know what I think about the bold print above is that Michael is terrified that they may of gave her a shot of what Dr. Hammesfahr uses on his patients.
My personal suspicion is that somebody associated with Michael tried to inject Terri with something but was unsuccessful. Why would Michael assume vague scratches were needle marks unless he had some reason to suspect needle marks?
