Angelo Ward was 25 when he was fatally shot outside his Baltimore home in December 2012. A promising super featherweight boxer, Ward’s death is described as retaliatory in nature — authorities believe the attack was meant as revenge against his best friend rather than Ward himself.

Investigators say the aftermath included interception of a vehicle carrying several men who police believed were en route to carry out a retaliatory act for Ward’s murder. Despite that dramatic development and a clear-seeming motive, no arrests or suspects have been publicly linked to the shooting and the case has gone cold in public view.

Who knew Angelo or had contact with him in Baltimore in late 2012 and might help finally identify who pulled the trigger?
