Keith Mason Jr. was 24 and from Chester, Pennsylvania, when he was killed on June 18, 2007. Known to friends and family as Kee Fee or Loyalty, he enjoyed singing and rapping and was remembered for his baritone voice.

His death is one of a series of unsolved murders in Chester that community group Women of Strength for Change grouped under the Chester 12 initiative to draw attention to the cases and press for justice. No arrests have been made in connection with his killing, and the case remains open.

Keith’s family and friends continue to grieve and seek answers, and the Chester 12 effort keeps his memory in public view. Does anyone who knew Keith or was in Chester in 2007 have information that could help?
