The trial of two men accused of trying to kill a witness ? and acquaintance of several years ? in a Baltimore County homicide began Wednesday in city court.

Victor Rickey Shuron Jr., 30, allegedly jumped out of a van Nov. 26, 2006, at the Waverly Shopping Center on the 2800 block of Greenmount Avenue and shot Donnie Hill, a witness in a county homicide case involving Shuron. His co-defendant, Yusuf Winston-Bey, 27, allegedly drove the van.
