Since I don't know the exact Rio Cutler in question, it's difficult to tell the true story. Maybe Rio Cutler is a local figure in a particular community, known for a unique event or achievement. Without more details, it's impossible to give a definite account.
I'm not entirely sure specifically which 'rio true story' you are referring to. It could be about a person named Rio, or it could be related to the city of Rio de Janeiro. Without more context, it's difficult to say exactly.
