Manslaughter conviction affirmed in fight over Canton parking place 

A man who killed an off-duty Baltimore police officer during a fight over a Canton parking space was properly convicted of involuntary manslaughter, the Court of Special Appeals held Monday. Sian James, 26 at the time of his April 2011 trial, said he acted in self-defense when he threw a piece of concrete at Officer Brian Stevenson’s head on Oct. 16, 2010.
