Drive to Francis' marker in Castle Gardens, watch the cut scene then get a cab to the next marker.
After Francis' phone call walk around to the north side of the building. Climb up the wooden boards to the scaffolding platform and over to the cleaning lift. Take the lift up to the roof and walk into the marker.
Shoot either Derrick or Francis. There's not a huge amount of difference between them, but if you shoot Derrick, Francis will allow you to lose a wanted level once before the end of the main missions, which is quite useful.
