Giddey is 21 now, he was 19 when this incident supposedly happened. He believed the girl he hooked up with at some club was also 19 at that time but she was actually 15. She is now 17 years old. So he allegedly slept with a 15 year old girl when he was 19. It's been 2 years since the incident.
FWIW the club they met at cards and only lets people in 18 or older. No word on how she got in. This whole thing is a mess. Since the girl involved and her family aren't pursuing legal action, I can't personally condemn Giddey. Not saying what he did was right but it doesn't appear as predatory as initially presented when the story broke. Age of consent is 16 in Oklahoma, with the girl being 17 and Giddey 21, currently, they could have a legal relationship in the eyes of the law. I don't believe they're seeing each other but I think that context adds a layer to things that makes things a bit murkier.
