VENTURA COUNTY, Calif. - Filed away in a drawer, a manila envelope held a secret for nearly 30 years.

It contained USC graduate Audry Nafziger’s medical records from 1992, when Dr. George Tyndall gave her a life changing diagnosis. USC’s only campus gynecologist told her she had a sexually transmitted disease and that he would need to take pictures for his records. 

“I felt his hands on my body – ungloved,” Nafziger recalled. “He could tell I was afraid and nervous and he took advantage. He closed and locked the door.”

Nearly 30 years later, in 2016, Ja’Mesha Morgan says Dr. Tyndall told her she might have AIDS and that she would need testing. Now, both women believe it was all a rouse to arrange a follow up exam. 

Through his attorney, Tyndall denies any criminal activity while at the university, but the Los Angeles Police Department has handed over 102 crime reports to the District Attorney regarding the doctor. 

Still, more than a year after LAPD opened the case, Tyndall is not facing any charges. 

The DA herself, Jackie Lacey, is also a USC graduate. She has refused to answer any questions about the investigation. And while she met with the university’s interim president, she has not met with any of the survivors interviewed by Spectrum News 1. 

Their stories span three decades, from those who graduated in the 90s, to Mai Mizuno who graduated this spring. All of them told their stories to investigators and are also suing USC. 

“It is difficult as a survivor to sit and wait when you know the person who did these things to you is walking free,” Nafziger said. 

Nafziger went on to become a prosecutor who spent half her career pursuing sex assault cases in Ventura County. She is among those who is angry Tyndall has not been arrested. 

“I’m concerned because he is a predator,” Nafziger said. 

The secret in the envelope? 

Nafziger’s actual lab reports from 1992, which came back negative for the STD Tyndall told her she had. A disease she disclosed to every sexual partner and doctor until last year when she looked inside and saw the truth.
