According to The Chicago Sun-Times, Belo, born Darnell Smith, will receive a 10-year sentence for the crime.
Prosecutors said Pinkston and Smith were watching two people fight, when Pinkston attempted to break up the ruckus.
Police said Smith warned Pinkston to stay out of the dispute and when he refused, Smith shot Pinkston to death on the street.
Smith’s girlfriend Felicia Hamiton, was also charged in the case, after she attempted to bribe witnesses $1,000 in attempt to get them to change their testimony against Smith and keep him out of prison.
“I think it’s a good outcome, and I thank God for it,” Pinkston’s brother D’Angelo Dixon told The Chicago Sun-Times. “I’m glad that guy got 10 years.”
Belo will be formally sentenced on November 8 in Chicago.
Group members Belo, Nard and AK-47 hit big when they collaborated with fellow Chicago rapper Twista for the hit 1996 single “Po Pimp,” taken from their album “Picture This.”
