Stubbs will inform Johnny that someone has sensitive information and is ready to go to the press. Quickly drive to the location of the informant and talk to him. He'll tell you he's going to the press and taking you down for a long time and will quickly drive away. Jump on your vehicle and shoot him through the window or blow up his car. Once he is dead, drive away and you will receive your payment and a call to Stubbs.
- For a quick way to get rid of him, use your shotgun (3-6 shots should do the trick).
- Try to use the zoom button when aiming (press the right stick in on consoles).
