Federal prosecutors are seeking many years in prison for a Monroe County father and his son who were convicted of growing marijuana in greenhouses.
Gerald Duval Jr. and son Jeremy Duval are returning Monday to Detroit federal court. The government says they "shamelessly exploited" Michigan's medical marijuana law to try to get around a federal ban on pot.
Prosecutors are recommending nearly 16 years in prison for the elder Duval and 14 years for his son. The greenhouses on Ida Center Road in Monroe County were approximately 100 feet long and 50 feet wide.
The Duvals admit they were growing marijuana but insist it was for medicinal use under Michigan law. Jeremy Duval says he thought the large operation was protected.
