His death is shrouded in mystery. There were no obituaries, no death notices. Victims were not notified of his death by the San Mateo DA's office. I just happened to learn about it today while looking at a civil suit brought against him by one of his victims. In the letter posted online by Ayres' attorney Constance Yu on May 9, 2016 , she state thats she had learned that "Dr. Doe passed away on April 20 or 21,2016."
You can see the letter online in this case: :Case CIV467273 - MANUEL DOE VS JOHN DOE 1
We don't know if he died in prison or at home. He died three weeks ago, and yet nothing from the San Mateo DA's office on this?
