A suspected overdose involving a 22-year-old is now the latest case Oxford investigators say may be connected to synthetic kratom. Police say the man, who is not a student, is expected to recover after synthetic kratom was found at the scene. The investigation comes as a father and son who worked at a vape shop face state and federal charges after authorities allegedly traced synthetic kratom sales to the store following the deaths of two Miami University freshmen. Investigators say more than 500 units of the product were seized. ▻
