Larissa needs us to pay a visit to the morgue as there is information about Ana there. If we can get in and retrieve the Medical Examiner's files, it may give us a clue as to what happened.
Once you get to the morgue you will see it is very heavily guarded, probably after all our activity there the last time. Because of this, you have to go round the back, via an alleyway. Climb the fence and go up the scaffolding to enter through the window as indicated by the objective arrow.
You will then be inside the morgue and can start looking around. The files are in the office upstairs, so exit the room you start in to the right, then go upstairs. There are, as mentioned earlier, a heck of a lot of guards in there, so you will need to be on your toes. Enter the room on the next level and retrieve the files. At this point, you will undoubtedly have 4 police shields as your wanted level, so continue on and down the next set of stairs, following the corridor to exit the building.
There should be a police car parked outside which you can use to make your escape, though you will then have to lose the cops. Find a police shield to lower your wanted level to three, which should make things easier. You can then return to Larissa with the files to complete the mission.
The Medical Examiner's files show that the body thought to be Ana was actually a homeless heroine addict, meaning that Ana must still be alive. On the bombshell, the chapter ends.
