Parker, who has not been identified as a member of the Hoover Crips, answered “Yes, sir,” and “No, sir,” to most of the questions posed to him by Dowdell during the 35-minute hearing.

Asked by the judge to describe his education, Parker said he needed 42 hours to graduate from college. He said he completed a 30-day drug rehabilitation program following his arrest in 2014.

Parker and his attorney declined to comment afterwards.

Since the indictments were announced, records show 27 of the 51 defendants have entered guilty pleas and have been sentenced or are awaiting sentencing.

Among those named in the indictment were Lorell Battle and Gaywone Blades, who were charged with conspiracy to commit murder and murder of a federal witness.

Battle and Blades were alleged to have conspired to kill Anthony Dejuan Campbell, whose bullet-riddled body was found April 3, 2013, near the driveway of his house on Garrison Avenue just south of 33rd Street North.

Federal court records show that about two months earlier, on Jan. 25, 2013, Campbell testified in the trial of three men whom prosecutors described as members or affiliates of the Hoover Crips who were charged and subsequently convicted in an armed robbery conspiracy.
