Lindberg wanted to celebrate that evening's Super Bowl XXX victory by the Dallas Cowboys by finding "a Jap". Lindberg and an accomplice, 17-year-old Domenic Michael Christopher, encountered Ly, who was rollerblading around the tennis courts at Tustin High School. Lindberg and Christopher trapped Ly on the courts, beat him, kicked him, and then stabbed him many times. Prosecutors also charged Lindberg with a hate crime and bullying.[6] Before that, Lindberg served most of a five-year prison sentence for another first-degree assault after shooting an 11-year-old boy three times with a pellet gun in 1992.[7]
