The nature of “investigation” is we don’t know, but USC suspended him. To me the online shoe selling sounds suspicious — was he and maybe other USC athletes trying to monetize the free athletic wear they get routinely and perhaps maybe getting special access to limited edition shoes from shoe reps trying to gain future shoe deals from these athletes?
Feel bad for students who, as I did, have to pay their own way with jobs that are currently on hiatus, cut-back hours, etc, due to COVID pandemic. Hope they are getting some relief.
