MI Doctor Convicted on Tax Charges Tied

What Happened

Peter Nwoke, 50, a Grosse Pointe Woods doctor, was convicted by a federal jury in Detroit in May 2026 on tax charges. Prosecutors said he failed to declare income from illegally selling controlled substance prescriptions, charging $500 per prescription for OxyContin 80mg or oxycodone 30mg, which buyers then sold on the street. The release states he prescribed over 2.8 million dosage units in the tax years at issue and underreported income by more than $2 million for 2011 through 2013. Sentencing is scheduled for September 10, 2026. Separate perjury charges remain pending.
