You should look at Penal Code sections 261.5 (b) and (c) which makes having sex with a minor by any person (not just an adult) a misdemeanor if the age difference is less than 3 years or a felony if more than 3 years. If you have some genuine basis for this accusation you could report it to the police or the DA. If you don't you should go back to minding your own business.Ask a similar question
If the 17 year old is more than 3 years older, it is a felony. If the 17 year old is less than 3 years older, it is a misdemeanor. It is a serious crime that can cause a lot of issues in the future, such as sex offender registration and mandatory sex counseling.
