Four men, including a Hampton University assistant professor, have been charged for their roles in a reported drug ring at the Newport News City Jail in Virginia, reports WVEC

Three of the men arrested are already inmates at the jail, according to authorities. Michael Cleary, 30, Daniel David Hogge, 50, and Shiron Lamont Gilliam, 38, were  arrested by Newport News Sheriff's deputies and now face conspiracy and drug possession charges. 

Officials say 40-year-old Sharrieff Rasheem De'Johnette, an assistant professor of history at Hampton University, sent the drug-filled mail. De'Johnette is now facing charges including drug conspiracy, distribution of marijuana and heroin and distribution of drugs to inmates. More charges are pending against the Williamsburg man following the search of his home, campus office and car. 

According to deputies, they seized mail in April that was sent to inmates. The intercepted mail included tobacco and rolling paper. Gilliam received heroin, while two of the men were sent marijuana, authorities said. Hampton officials say De'Johnette has been suspended without pay.
