Seems Dr. Graves eventually died of AIDS. Obit:
In March 2009 his suit against the government for disclosure of its
role in the development of AIDS was accepted. The Justice
Department is engaged, and lawyers have been assigned to the
case.
Soon after, his health began to deteriorate.
The other thrust of Dr. Graves work was his interest in having a
certain AIDS cure tested clinically. This was Tetracyl, a
silver oxide, patented by Dr. Marvin Adelman as a cure for the
HIV virus. The efficiency of this treatment has not been
researched. Some patients have reported eradication of the
virus, other, usually more advanced, cases have not responded.
After March Graves continued to lose ground. He tried another
injection of Tetracyl, but the results were not positive. He
had a bone infection and his T-cells were down to 20. Valiently
putting his life on the line for what he believed, he elected
for one more Tetracyl before he resorted to retrovirus
medications.
Last Monday night he had severe chest pains and his excellent
caretaker-boys took him to the hospital. Next morning he was
intubated, comatose, and incommunicado. Thursday morning his
sister called and said he had an intractable lung infection. He
was to be put on "comfort care" at 2:30, meaning life support
would be withdrawn and more morphine would be applied.
He died that afternoon.
