The conviction of the leader of a violent cocaine trafficking organization and two of his lieutenants will make Baton Rouge a safer place, the Baton Rouge area’s chief federal prosecutor said Wednesday.

Jeffery D. Perry, 31, Jermaine J. Chapman, 32, and Charles Boyer, 50, all of Baton Rouge, were found guilty late Tuesday on federal drug counts and face lengthy prison terms.

Perry, the leader of the drug trafficking group, and Chapman also were convicted on firearms charges following a multiweek jury trial in Baton Rouge federal court.

“Baton Rouge is truly a safer place without these defendants on the streets,” U.S. Attorney Walt Green said. “The level of violence and depravity engaged in by this group made this prosecution essential.”

Perry, who faces a mandatory minimum prison term of 45 years, was convicted of conspiracy, seven other drug trafficking charges involving crack and powder cocaine, carjacking, and five charges involving the possession and use of firearms while being a felon and in furtherance of crimes of violence and drug trafficking.

Chapman, who faces at least 25 years in prison, was found guilty of conspiracy, six other drug trafficking charges involving crack and powder cocaine, and possessing a firearm in furtherance of drug trafficking.

Boyer was convicted of conspiring to distribute crack and powder cocaine and faces at least 10 years behind bars.

A sentencing date has not yet been set.

A fourth man, Eugene Williams, was acquitted.

Four other defendants previously pleaded guilty to their involvement in the drug trafficking conspiracy.

“I am very proud of the prosecutors and agents who worked so hard to ensure that justice was done,” Green said. “This is another great example of how federal, state and local collaboration can make our communities safer.”
