Case 1224-8: Amusement Mile Mauling | Casefile Reports Batman: AO Guide
Last update: 11 May 2016
Circumstances of unlocking the case: This case becomes available while exploring freely the game world, and more exactly The Amusement Mile (there will appear a notification on the screens and the entry concerning the mission will appear in Batman's journal). Most probably, this mission unlocks after the completion of the game.
The location where the investigation starts is the crime scene shown in the screenshot, which is located in the Northern part of The Amusement Mile district, close to the Gotham Casino entrance. After you get there, listen to Batman's commentary and activate the evidence scanner.
Start by scanning the corpse, thanks to which you will determine the victim's identity. Remain here and scan the DNA traces, so that Batman can work out the preliminary version of the reconstruction.
You now need to start using the keys/triggers to manipulate the replay process and follow the red line. This will allow you to determine the place that you need to jump down in (the screenshot). After you land in the next location, activate the evidence scanner again and scan the region of the fan, thanks to which you will analyze fingerprints and identify the murderer.
This is not the end, yet because you still need to arrest Andrew Carter, i.e. the perpetrator of the murder. You can find him in the central part of the Park Row district. Since Andrew is surrounded by several allies, it would be a good idea to plan on the attack.
After the fight proper starts, attack all of the enemies. As you have probably figured out, Carter is an "elite" enemy, which makes it even more considerate to leave him for later and deal with him with a series of quick blows or the shock gloves. As far as the remaining enemies are concerned, they will not be too difficult to defeat but, you should make sure that they do not get the chance to use guns. After you have sufficiently weakened Carter, there will appear an option of interrogating him (by pressing the appropriate key/button). Andrew will admit to having committed the murder and the investigation will close.
