Niko meets Brucie Kibbutz at his garage in BOABO. Brucie explains that Lyle Rivas has not repaid money he owes to Brucie, and he wants Niko to kill Rivas, and suggests Niko locate Rivas using a Police Computer. After stealing a police car and accessing the computer, Niko finds Rivas' address in Rotterdam Hill, Broker, on the database and heads to his house. Niko arrives at Rivas' house and confronts him, but Rivas jumps out of the window and drives off in his car. Niko chases after Rivas and eventually kills him after a long car chase. Niko phones Brucie and informs him that Rivas has been killed, and Brucie thanks Niko.
