does cybercrime do shit

one of my friends junior who is 14 is dating a 20 ur old man. we got proof by texting the man w a fake ig account. they have a physical relationship too and it's just really gross. and we didn't know what to do so we told the school. next day she gets suspended. and now she wants to take the account to cybercrimes to figure out who it is should we be shitting ourselves? we didn't do anything wrong?
