A Frankfort man who authorities say grew 3,200 marijuana plants in 2011 will now spend the next 12 and a half years behind bars. Corey Leitz was sentenced on Thursday in federal court. Authorities say Leitz maintained the growing operation on McIntyre Road and sold the drugs to numerous customers in Herkimer County and elsewhere. After serving time behind bars, Leitz will be under supervised release for five years.
