Retired agent Judy Tyler served 31 years with the FBI. In this episode of FBI Retired Case File Review, Judy reviews her investigation of the Maurice Lewis, aka “Mo Black,” 8th and Allegheny cocaine criminal enterprise and the surprising spin-off case involving the theft of Philadelphia’s historically significant architectural treasures that resulted in the conviction of Charles Kass, a former IRS and Labor Department agent. Judy has extensive experience in the investigation of violent drug trafficking organizations and advanced investigative techniques. She specialized in the recruitment, development, and operation of human intelligence, also known as informants, and cooperating witnesses. During her career, she received awards from the Mid-Atlantic Region of the Organized Crime Drug Enforcement Task Force (OCDETF) and from the United States Attorney’s Office, Eastern District of Pennsylvania. Post-retirement, Judy continues to share her experience and expertise as a contract instructor training current FBI agents as part of a specialized in-service program. (In Episode 3 of FBI Retired Case File Review, Judy was interviewed about two other drug investigations and her FBI career.)

Mo should be free today, they put him under the jail, he got life +5 years because he had a gun on him at the time of his arrest. He never had a violent crime on his record, all he did was sell drugs. They could’ve gave him 25 years and that still would’ve been a lot.
But I am sure they hated Mo, he was black as the ace of spades and was flashy. When the Cadillac’ Escalade first came out in 2000 he had one painted lime green with Ooh Wee written in pink on the side, he had Platinum Bound records. Mo wore a gold chain so thick you could’ve locked your bicycle up with it. He had 100s of houses, some of them were filled like mini warehouses with just sneakers in them.
Free uncle Mo.
Jimmy – FBI agents investigate and testify, but judges determine how much time someone gets. The one thing we all know about the justice system is that the sentence each person receives can vary dramatically. The system is definitely not fair or equal. Thanks for listening to the episode. — Jerri
