SHEBOYGAN, Wis. (WHBL) - A Sheboygan drug dealer is going to prison. 38 year old Marcus Henry, who was convicted by a Sheboygan County jury two weeks ago, was sentenced recently by Judge L. Edward Stengel to 15 years in prison to be followed by 10 years on extended supervision. Henry had been under surveillance while dealing cocaine in the city of Sheboygan in October of last year and was arrested after officers witnessed a drug transaction. They later executed a search warrant and found cocaine hidden behind trees and shrubs outside of an apartment in the 1400 block of South 38th Street, where Henry had been staying.
