Worcester State's Attorney Beau Oglesby said he will ask for the maximum sentence of 30 years at an upcoming sentencing hearing.
"If I could ask for more, I would," said Oglesby after the jury returned its verdict.
"Considering the facts of the case and the evidence of the case, we can understand it," said Oglesby.
Jurors began deliberating just after 11 a.m., with an outburst from the defendant fresh in their minds. During Oglesby's closing statement, Ballard began arguing from the defense table, saying he was "irritated." While being removed by deputies Ballard threw several pieces of paper into the air.
"I called the police every time," Ballard said in court. In interviews before the trial, his family members said Ballard had arguments with Bailey and a few of Bailey's friends in the weeks leading up to the incident.
During just over an hour of deliberation, jurors weighed lengthy witness testimony including that of three men who said they saw a gun present during the fight between Ballard, Bailey and Martel Blake.
Several witnesses said at least three men threw rocks and spit on Ballard minutes before the stabbing.
Ballard will remain in jail until he is sentenced in about 60 days.
