A woman in California used YouTube to expose a teacher she says sexually abused her years ago.
She called the teacher and recorded their conversation on video.
The woman, who goes by "Jamie," is now 28.
She says the abuse started when she was 12, but she only just recently got up the courage to report it.
She thought with the statute of limitations, the video was the only way to make her teacher pay.
Shortly after "Jamie" posted the video, the teacher quit and police did start an investigation.
Authorities say they won't know if there can be any charges, until they know exactly what crimes may have been committed and when they happened.
CNN has reached out to the teacher but she has not responded to calls or e-mails.
