The Toronto Sun  (Frank Zicarelli) reports:  Of the many characters to play in Toronto, few could match Keon Clark, whose demons continue to haunt him. On Thursday, Clark was convicted on a misdemeanour weapons charge stemming from a March 2006 incident at his Danville, Ill., home. He faces a year in prison. The ruling follows Clark’s bench trial for possession of a firearm without a valid card. Yesterday, he was scheduled to stand trial on disorderly conduct for filing a false police report in January 2007; criminal damage to property over $300 US in September and three driving infractions stemming from two incidents in March 2007 and one in July.
