That scumbag McAffrey, he took more bribes than anyone. He thinks hes gonna get an honorable discharge if he turns states evidence.
He just squealed! Hes under armed protection in WitSec property down in Newport, some apartment behind the car park.
Torch that place, that should flush em out, and youll hunt em down, make sure he never talks to nobody.
For this mission, I suggest a Linerunner or similar large vehicle which you will use to block an exit.
The building is next to the PaynSpray near the multilevel carpark, and the exit to block is the one right next to the ramp (on the left, not the long one that leads to Asuka) its a small ramp leading to the street.
Once its blocked, lob a grenade into the window (in the cutscene) and the car will come screaming out, but it will be blocked by the vehicle you parked there.
Blow it up with grenades, and the mission is over.
