It might be too late to prossecute the crimes against you, but you could still report it and be a wittness to his past offenses should someone younger comes forward to press charges. I did this at 31, long, long after statute of limitations. I knew he did it to others back when I was a kid, why would he have stopped? I figured at least a visit from some detectives might at least get to him somehow. I imagined him pissing his pants after answering the door, I would've loved to have seen that
I contacted the county prossecutor's office after hearing that my perp (uncle) was baby sitting his grand daughter. Doing this also meant that I would be telling the rest of the family which I did. When I called the prossecutor's office, they told me to come down to make a report in person, it was a scarey idea at the time, but once I started it was ok. I felt good leaving there, kind of enpowered.
