Coventry Tower Deathtrap

The Coventry Tower Deathtrap was an event that occurred during the Christmas Eve incident that led to the murder of David Shannon.

Arkham Origins Incident
Around Christmas Eve, Coventry's network tower was sabotaged by Edward Nashton, the head of GCPD's Cyber Crime's Division, at the request of Black Mask, (or rather, someone posing as him) to prevent Batman from using his Batwing at various points of the city. Knowing that Gotham Optics will send a repairman to fix the damage to the tower, Nashton hired a low-level criminal named John F. Baker to rig the security panel to the tower to detonate if someone from Gotham Optics were to swipe a key card. Baker left his fingerprints on the panel. As Nashton predicted, Gotham Optics did indeed send someone, David Shannon, to fix the network tower. Shannon, not realizing the danger, swiped his Gotham Optics key card on the booby-trapped panel, detonating it. He was bodily hurled across the room and smashed through a wall killing him in the next room. After this, Nashton only had to clean up loose ends. Luring Baker to the Diamond District, Nashton then murdered him, with his body eventually being discovered.

Under an hour later, Batman, trying to access the tower, discovered the damage from Nashton's earlier work including David Shannon's corpse and, deducing that the damage wasn't caused by the severe blizzard outside, set up a crime scene. Upon discovering the fingerprints on the panel and deducing it was booby-trapped, Batman sent the DNA evidence to his manservant, Alfred Pennyworth, and learned that not only did the prints belong to John F. Baker, but also the fact that he had died at least an hour prior, causing the vigilante to deduce that someone, most likely the person responsible for having Baker sabotage the device, decided to tie up loose ends. Batman eventually found the card key and scanned the codes for his Cryptographic Sequencer to bypass the boobytrap. After getting into the tower, he then met the man responsible for the sabotage, Enigma, and proceeded to fix the device.

Casefile details
Batman: I don't think this tower malfunction is from storm damage. I need to set up a crime scene and find out what happened. I should start by identifying the victim.

Body scan of the victim "Victim ID Fingerprint analysis Name: David Shannon Occupation: Technician Employer: Gotham Optics Priors: None"

- Head scan results of victim

Batman: Victim's name is David Shannon, a Gotham Optics employee sent here to repair a faulty network tower. But what killed him? Scanning the DNA Impact on the wall should provide an answer.

Scan of DNA impact on the wall "DNA Analysis Impact pattern Analysis: Killed by impact Cause of death: Head trauma Impact energy: 1114 Joules Cause of impact: Thrown by explosion Note: Explosion caused by access panel"

- DNA analysis results of spot on wall

Batman: Impact analysis indicates the victim was killed by some kind of explosion, originating at that access panel. I should scan it for additional clues.

Scan of panel "Suspect ID Fingerprint analysis Name: Unknown Status: Unknown"

- Handprint analysis on panel (first scan)

"Suspect ID Fingerprint analysis Name: John F. Baker Status: Deceased Priors: Robbery, Breaking and Entering"

- Handprint analysis on panel (after calling Alfred)

Batman: It looks like the panel was rigged to detonate when swiped with a keycard. Someone really didn't want this tower repaired. And it looks like that same someone left a set of fingerprints behind. Alfred. I'm uploading some prints for anaylsis. Let me know what comes back.

Alfred: Certainly, sir. Searching now... And here we are: They belong to one John F. Baker. He's a rather unremarkable criminal. Small jobs, mostly. Only... That's curious.

Batman: What's curious?

Alfred: Mister Baker's dead, sir. His body was recovered from the Diamond District just under an hour ago.

Batman: Looks like someone's tying up loose ends. I can bypass the booby-trapped access panel with my Cryptographic Sequencer. But I'll need the encryption codes from the Victim's access card. Reviewing the crime scene should show me where it is.

Scan of discarded access card "Digital Data Analysis Analysis Type: Municipal Security Codes Note: Allows decryption of security consoles"

- Digital data results from dropped cell phone

Batman: This card has the codes I need to hack any of the network tower's access panels.

Trivia

 * The Coventry Tower deathtrap is one of only two casefile events that are mandatory to complete the game, the only other being the Lacey Towers Murder.
 * It is also the only casefile event in the game where the perpetrator is not brought to justice, as John F. Baker was murdered an hour before Batman arrived at the scene of the crime, and Enigma had managed to flee the scene after Batman foiled most of his plans.
