Meet Malik on the roofEdit
After dealing with Zeke Sanders, go through the door. On the right you will see police trying to break open a door if Sanders escaped. On the left is the door to the helipad. If both Greg and Josie Thorpe survived, you can talk to Greg here and tell him that his wife is fine, leading to him promising you a reward for your work. He will also apologize for doubting you if you had not reassured him of his wife's safety earlier.
