Case 1224-7: Coventry Fire | Casefile Reports Batman: AO Guide
Last update: 11 May 2016
Circumstances of unlocking the case: This case may become available during the free exploration of the game world, in the Coventry district (there will appear an appropriate notification on the screen and the first entry, connected with the crime, in Batman's journal).
This investigation starts in the location of a recent fire shown in the screenshot), which is located in the North-Western part of the Coventry district. After you get there, listen to Batman's commentary and turn on the evidence scanner.
Start by scanning the corpse to determine the murdered person's identity on the basis of fingertips.
Remain at the corpse and scan the DNA trace next to it, which will lead to playing of the preliminary version of the reconstruction. The next step is to scan the area where the fire started.
You now need to manipulate the playing of the sequence using the appropriate keys/triggers and by following the red trace. Doing this will allow you to determine that you need to climb over a nearby wall using the hook.
After you reach the ledge above, you need to find another trace on one of the walls. Finally, scan the ladder on the ground, thanks to which you will identify the murderer.
This is not the end yet, because you need to arrest Quing Lu, i.e. the hitman responsible for the murder. He is staying aboard the Penguin's ship [The Final Offer], i.e. in the North-Eastern corner of the map. After you get there, access the ship using the hook. Start attacking the characters staying there. You need to take precautions because Quing Lu is a martial artist. As you can probably remember, this kind of enemies are capable of countering some of Batman's attacks and, furthermore, they usually land two blows at a time, which forces you to be more careful while countering these blows.
Leave the murderer for the end because there will appear an option to interrogate him, after you have sufficiently weakened him ( pressing the key/button displayed on the screen) Quing Lu will admit to having perpetrated the act and the investigation will be over.
