A friend discovered her body in the front room after finding the back door had been kicked in.

Arnold’s family says she had been publicly pursuing justice for her grandson, Shelbyon Polk, who had been killed a year earlier, and had used social media to seek leads. Her family notes a history of violent losses, including unsolved murders of her grandson’s father and grandfather. More than two years after the killing, James M. Cohen, then 34, was charged with first-degree murder and armed criminal action in Arnold’s death, and Wayne H. Rogers, then 25, was charged with hindering prosecution for allegedly helping Cohen and others flee the scene. Court documents did not immediately establish a clear motive.

Arnold was a mother of five and grandmother of fifteen, remembered by relatives as caring and determined. Does anyone in the Kirkwood or Meacham Park area have information about that night or about threats she may have reported?
