Tracking down the elusive serial killer in Batman: Arkham City requires keen detective skills and a thorough understanding of the sprawling megaprison layout. The Identity Theft side mission introduces players to a grim mystery involving a criminal who leaves a trail of faceless victims scattered across various districts. Successfully completing this investigation requires finding three distinct crime scenes before tracking the culprit to his final hideout.

Discovering the First Victim in the Industrial District

The dark investigation begins in the southeastern section of the prison grounds, where the initial body can be found lying in a secluded alleyway. Players must utilize Batman's advanced Detective Mode to scan the area and uncover critical forensic clues left behind at the scene. This initial discovery sets the narrative in motion and alerts the Dark Knight to a highly calculated plot operating within the facility walls.

Investigating this first crime scene allows players to analyze the specific surgical precision used by the mysterious attacker. It becomes clear that the assailant is targeting individuals who bear a striking resemblance to notable figures outside the prison. Gathering these initial clues is essential for unlocking the subsequent phases of the tracking sequence.

Locating the Second Crime Scene Near The Bowery

As you progress further through the main storyline, the secondary victim appears in a narrow corridor situated just north of the subway station entrance. Navigating to this location requires bypassing several groups of hostile inmates who patrol the surrounding rooftops. Once the area is cleared, players can safely activate their scanning equipment to catalog the fresh evidence.

The forensic data retrieved from this second individual provides a deeper look into the killer's sinister methodology. Each crime scene forces players to cycle through different diagnostic layers to isolate biological signatures and unique chemical traces. Uncovering these specific markers helps narrow down the potential identity of the psychological profile responsible for the gruesome acts.

Tracking the Third Body in the Amusement Mile

The final victim needed to pinpoint the killer's location is situated in the northern section of the map, tucked away near the flooded city streets. Finding this body can be challenging due to the vertical nature of the surrounding architecture and the lack of immediate visual landmarks. Meticulous exploration of the lower walkways will eventually reveal the target hidden behind a large concrete barrier.

Scanning this final location completes the physical evidence collection phase and allows the Batcomputer to construct a definitive path forward. The cumulative forensic data points directly to a secure apartment building where the mastermind has established his temporary operating base. Reaching this milestone ensures that players are fully prepared to confront the villain directly.

Confronting the Mastermind in the Hideout

With all three crime scenes fully processed, a new waypoint will appear on the map leading directly to a locked room near the courthouse. Entering this secure location triggers a cinematic sequence where the full extent of the architectural deception is finally laid bare. Players will uncover the shocking motivation driving the entity behind these elaborate identity thefts.

Resolving this encounter successfully grants players substantial experience points and concludes one of the most compelling narrative threads in the game. Understanding the exact placements of these bodies saves valuable time and ensures a smooth progression toward full completion status. Mastering these tactical tracking steps allows you to efficiently deliver justice to the dark streets of Gotham.
