Rapper FBG Duck was shot and killed earlier this week in his hometown of Chicago, which Lupe Fiasco found out about on IG Live. 

The "Kick, Push" rapper, who's also from Chicago, said he never met Duck but thinks he was really talented. Lupe also said there will be major payback for his murder.

"Wow. That's terrible," said Lupe once one of his followers told him the news. "He was really, really good ... Unfortunately, we're going to have a few murders now and retaliation to this. I hope that's not the case but this is what it is in the city."

FBG Duck was only 26 when he was killed.
