The victim was not one of Giannini’s students, said San Mateo County District Attorney Stephen Wagstaffe.
Investigators first flagged Giannini after a video of her and the girl was uploaded online, Wagstaffe said. A schoolmate of the victim saw the video and reported it to their principal.
The alleged incidents occurred in 2014 and 2015, when the girl was under 16. Prosecutors believe the girl posted the video.
“We know the victim was sexually active, and there were a lot of videos that were uploaded,” Wagstaffe said.
Giannini was working as a substitute teacher when she was arrested, Wagstaffe said. He did not know which school.
She worked at St. Elizabeth Seton School in Palo Alto for the 2016-17 school year, said Liz Sullivan, spokeswoman for the Catholic Diocese of San Jose. During that time no allegations were made against her, Sullivan said.
Giannini appeared in court on Thursday and did not enter a plea, Wagstaffe said. She is due
back in court Nov. 5.
