A Martinsville teenager accused of shooting his classmate on Friday waived his right to trial by jury. A judge will decide if Michael Phelps, 16, is guilty. Phelps is facing a number of charges in the shooting of 15-year-old Chance Jackson at Martinsville West Middle School on March 25. Among those charges is attempted murder. Another charge of battery was recently upgraded to "aggravated battery," which could add up to eight years of prison time if he is convicted.
