Yeah, I’m not saying anything about his life looks innocent but rather than he had more opportunities to accumulate wealth than just Wexner. Some of those would have been perfect money laundering vehicles (e.g. I “invest” in your fund and don’t complain when the management fees are high) so it seems like there should still be an investigation into still living partners.
It’s entirely possible this is the more mundane “rich people taking care of their drinking buddy” corruption, too - there’s certainly tons of precedent for that.
