Yes, but I'm sure there are cases where even if that happened they might not pursue charges. Let's say a high school senior who's 18 dated a high school junior who was 16 or they had an encounter. then years later, they bring that relationship up because that senior went on to be rich etc.
I'm not saying that's what happened here, there's still little to no details which is mind boggling to me that a team's best player who's competing for a WS can be suspended like this and there's no real substantiated information out there in the public.
From that Passan ESPN article..
"About a month earlier, a different girl contacted police to discuss Franco, according to Diario Libre, a Dominican newspaper. Prosecutors in Peravia, the Dominican province where Franco grew up, acknowledged that an investigation into him is open and being run by a unit that focuses on minors and gender violence. The lead prosecutor, Olga Dina Llaverias, is well known in the country as a specialist in child abuse cases."
I mean what would be the hold up...? if someone reported this to LE in the United States, they would move to arrest the person quickly if there was any real evidence that it happened.
