Alonzo is a henchman of Teddy Benavidez. He hangs around the apartment block in Northwood. When Ray Boccino sent Niko Bellic to kill Benavidez, he told Niko that Alonzo may inform him of Benavidez's location. After Niko found him, he punched him or aimed at him with a gun to rat out Benavidez's location. Niko can kill Alonzo, resulting in the fact that he will not inform Benavidez that Niko is coming for him.
