Today, a conversation with William Purpura, a Baltimore attorney who was a member of the legal defense team for Joaqu\u237\un Guzm\u225\un Loera, the notorious Mexican drug kingpin also known as ----El Chapo.---- Guzman was convicted in a Brooklyn courthouse last week on charges related to his illicit drug enterprise. The guilty verdicts, on all 10 counts, came after a three-month trial, and for federal prosecutors, three decades of investigation into the huge drug trafficking enterprise known as the Sinaloa Cartel. It was one of the most high-profile federal drug prosecutions in history. William Purpura has been involved in several recent high-profile cases, including the defense of Daniel Hersl, one of the Baltimore City police officers convicted in the Gun Trace Task Force scandal, and Michael Vaughan, a former MD Delegate from Prince George’s County, who was sentenced to four years in prison in a bribery case last September. Mr. Purpura joins Tom in Studio A. We have live-streamed this conversation on WYPR Facebook page.
