When Coolio's son, Grtis Ivey, is sentenced in September he could be looking at up to 10 years in a Nevada prison. The oldest child of Coolio pleaded guilty to felony robbery in a deal with prosecutors. He will be sentence to a minimum of 3.5 years in jail. He was arrested back in November when he broke into an apartment with a gun, forced the person living there into the bathroom, while Grtis' hooker girlfriend looted the place. Most kids just ask their parents for $50. Of course that could have been tough considering Coolio at one point was in jail with his son.
