Christopher Coke, a Jamaican drug trafficker whose arrest last summer came after a monthlong manhunt that left scores dead in Kingston, pleaded guilty on Wednesday to racketeering conspiracy charges in Federal District Court in Manhattan.
The guilty plea emerged during an hour of quiet dialogue between Mr. Coke and a federal judge, a proceeding that stood in sharp contrast to the violence generated last year as the Jamaican authorities searched for Mr. Coke, a neighborhood don, at the request of American prosecutors.
