Charges were filed Monday against Andrea Michelle Cardosa, 40, who was investigated after one of her accusers spoke out on YouTube, the Los Angeles Times reported.
Two victims have been identified, prosecutors said. Jamie Carillo, 28, said Cardosa began sexually abusing her in the late 1990s when she was an eighth-grader. An attorney for the other woman alleges Cardosa abused his client in 2009 and 2010, when she was 14.
Carillo secretly recorded then posted a phone conversation with Cardosa. Since it was posted Jan. 17, the video was viewed more than 1 million times but has since been removed.
In the 9-minute recording, Carillo is seen dialing a number using speaker-phone mode. After connecting with Cardosa, a vice principal at the high school, Carillo tells Cardosa she "brainwashed [and] manipulated" her as a child and "ruined my childhood."
"And every day when I think about what you did, you sicken me," Carillo said.
"I regret it every day," the woman on the other end of the line said. "Every day."
Alhambra Unified School District Superintendent Laura Tellez-Gagliano said school staff received an email that included a link to the video the day it was posted, and reported it to police, the Times reported. Cardosa resigned hours later.
Before working with the Alhambra school district, Cardosa worked for three other school districts as a teacher, administrator and coach. The Times said officials in those districts said she passed the necessary background checks each time she was hired.
