Track down all ten briefcases and kill Joseph Demarco with this complete guide.
None of these missions open up until Act 2 – A Risky Bid has been completed. It’s best to unlock all the ctOS Towers for these missions as they require a lot of back and forth across the map, so using fast travel is the best option.
For each of these missions you need to do two things; locate the Buyer and hack their phone, then track down a briefcase. In order to get the bonus mission to unlock, you must locate 10 buyers and 10 briefcases. Here’s how:

go over to Joseph Demarco’s place and hack in through the intrusion box. Once you’re looking inside Demarco’s lair, hack into the police officer’s cell phone to progress to chasing down and killing Joseph Demarco.
Out of Business
As soon as you have control of Aiden again, grab a vehicle (preferably and reliable, fast one) and set a waypoint somewhere along his route so you can just get ahead of him. Don’t drive past his convoy or he’ll start running scared and you’ll lose the element of surprise.
Once you’re ahead of him find a good intersection and park your vehicle there, before laying down three or four IEDs across the road. Once the convoy approaches trigger the explosions and watch the chaos unfold. If that hasn’t killed Demarco, take out the tires on his vehicle and finish him off. If he manages to drive off hack anything you can to slow him down.
You’ll now have a fair few cops on your tail, so make sure you’re able to escape as quickly as possible. you have now completed the Human Traffic Investigations missions and unlocked the Revoking Client Privileges award.
