Special Re-Post: Family Members of Mumia Abu Jamal and Troy Davis Speak on Their Struggle.

Thanks for joining us for another edition of "On the Block," a radio program that takes a critical look at the United States criminal justice system.

On today's show, we will hear from the relatives of two prisoners on death row. One is that of Wayne Alexander, the nephew of Mumia Abu Jamal. In the 1980s, Mumia was convicted of the murder of Philadelphia police officer Daniel Faulkner. He currently sits on death row. Mumia and his supporters have for years proclaimed his innocence; demands for his release have been the focus of a large international movement for the last two decades. Wayne provides us with a perspective on how Mumia's family has been grappling with his imprisonment over the last 20 plus years.

The other voice is that of the older sister of Troy Davis, Martina Correia. Davis is currently sitting on death row for a crime that many believe he did not commit. Martina Correia has been fighting for the release of her brother, Troy Davis, for more than two decades. While battling cancer, she has taken up the fight for her brother who she and many others believe was wrongly convicted for the killing of a Georgia police officer. We talk with her about the status of the case.
