A federal judge in Springfield sentenced two Chicago men who organized a large-scale cocaine trafficking ring in Quincy to federal prison.
Sylvester Purham, 24, and Howard Purham, 21, will serve 30-year and 20-year federal prison sentences, respectively.
A judge handed down the sentence Thursday.
The pair pleaded guilty to conspiracy to distribute more than 280 grams of crack cocaine in an investigation that spanned from August 2010 to November 2011. The two were arrested in January.
The federal criminal complaint said that the two helped orchestrate the operation that saw them transport drugs from Chicago to Quincy via Amtrak trains.
The two were associated with the Black P-Stone Nation street gang.
The two were also accused of threatening government witnesses.
