A 47-year-old man convicted for his role in a Lawrence cocaine trafficking ring has received a 12-year federal prison sentence, according to Acting U.S. Attorney Marietta Parker’s office.

U.S. District Judge John Lungstrum handed down the sentence Monday to Leland Roebuck, formerly of Lawrence. Roebuck pleaded guilty in January to one count of conspiracy to distribute or possess with intent to distribute more than five kilograms of cocaine.

In his plea, Roebuck admitted he was part of a trafficking conspiracy in Lawrence that lasted from 2000 to 2006, led by co-defendants Gerald Dunn and Shaune Frazier. Prosecutors said Dunn and Frazier would rely on Roebuck and others to distribute crack from an apartment in the 400 block of Wisconsin Street.

The conspirators also used an apartment in the 2400 block of Alabama Street, according to court records.

Nine other co-defendants in the case are scheduled to be sentenced later in May.
