• Manny wants you to take out some trash talkers riding on the L train. Go to the Algonquin bridge. When you arrive the train is leaving, so you'll need to follow it while in the car. Your best bet is to stick to the streets that are located directly under the tracks. Eventually the train will come to a halt and the targets will exit, you need to kill all three while they are still inside the train station.
