Tracking down the elusive serial killer in Batman: Arkham City requires a sharp eye and a thorough understanding of the game's gritty urban layout. The Identity Theft side mission tasks the Dark Knight with investigating a series of gruesome murders where the victim's faces have been meticulously removed. Players must actively search the open world to trigger each stage of this mystery, which eventually uncovers a chilling plot involving an iconic villain.

Finding the First Victim

The dark investigation begins in the Industrial District, where the first victim can be found lying in a secluded alleyway. Scanning the body reveals crucial forensic evidence and clues that point toward a highly organized killer operating within the prison walls. Initiating this crime scene investigation will officially add the quest to your active mission tracker.

After analyzing the blood splatter and interviewing a nearby political prisoner, Batman determines that the killer is targeting specific individuals. This initial discovery sets the narrative foundation for the rest of the dark case. Players should ensure they thoroughly scan all available evidence before moving to subsequent districts.

Locating the Second and Third Crime Scenes

The second victim does not appear immediately and is typically discovered in an alleyway located in the Bowery region. This body stands out clearly because the victim is shirtless, making it easier to spot even without relying on your detective vision. Investigating this location reveals another piece of the anatomical puzzle that the killer is assembling.

To discover the third victim, you must advance further into the main story until the city is in lockdown. The final body is situated near the outer wall of the Amusement Mile, tucked away in a narrow corridor. Completing the forensic scan at this location will allow Oracle to trace the chemical markers back to a specific hideout.

Confronting the Identity Thief

Once all three crime scenes are fully resolved, Batman receives the exact coordinates to a secure apartment hidden within the Bowery. Entering this facility reveals a disturbing laboratory filled with surgical equipment and medical notes detailing the gruesome procedures. Interacting with the central control panel triggers the final dramatic confrontation of the side quest.

The culprit is revealed to be Thomas Elliot, famously known as Hush, who has stolen the physical features of Bruce Wayne to escape the city undetected. Although he manages to temporarily slip away, solving this case completely fills out your mission progress report. Successfully finishing this assignment is mandatory for players aiming to achieve total completion in Arkham City.
