That's an unfortunately common occurrence when the police are brought in for crimes like this. Most sexual abuse is perpetrated by people who have a relationship with the victim, usually family. 1 in 5 women have been raped, a third of those women were raped between the ages of 11 and 17. 81% of women will experience some form of sexual harassment or assault in their lifetimes. Only 20-40% of rapes are reported to the police. Only about half of those result in arrest. 80% of the arrests are prosecuted. 58% of the prosecutions result in conviction. And 69% of the convicted offenders will serve time in jail/prison. So for every 100 rapists, about 3 of them will go to prison.
