Biography
Robert Joyner was a member of the Philadelphia Black liberation group known as the Revolutionaries and one of the defendants convicted after the August 29, 1970 Cobbs Creek confrontation with police. He received life imprisonment for murder plus a consecutive term for explosives offenses. A 2023 report on aging people in Pennsylvania prisons identified Joyner, then 80, as still serving the life sentence at SCI Phoenix and described an effort to obtain compassionate release. His Pennsylvania prisoner number is AF-3793.
Birth year estimated as circa 1943 from WURD Radio’s July 11, 2023 report identifying Joyner as 80. Age 80 on that date permits a birth in 1942 or 1943; an exact birthday is unconfirmed. The report’s caption identifies Joyner in the center of the group photograph. Source.
