Bomb Alert on Grimsborough

Blood on the Trading Floor is a case featured in Criminal Case, appearing as the twelfth case of the game as well as the city of Grimsborough. Also, it is the first case to take place in the Financial Center, a district based in Grimsborough.


The victim was a stock trader named Samuel Rye, who was found hung up in the Stock Exchange and emptied of his insides.

During the murder investigation, Jones gave the player two new forensic mini-games to use: A forensic brush that forensically dusts hidden fonts for clues, and a database-comparison mechanism, in which the player has to match four things to reveal the next move based on the data stored on the database of the police squad.

After thorough investigation, the killer was incriminated to be a stock trader named Harry Krane

Alden Greene needed a new stock trader, so he wanted to hire Samuel. Harry did not like it when Samuel kept on bragging about his deal with Alden, and as a result, he got jealous and disemboweled Samuel with a samurai sword, and hung the victim up in the Stock Exchange.

Judge Hall hereby sentenced Harry to life imprisonment with no chance for parole.

  • The case's title is an allusion to Michael Jackson's single, "Blood on the Dance Floor".
    • It could also be a reference to the 2000 American psychological black comedy film American Psycho.
  • In the Additional Investigation of this case, a developer oversight can be spotted: when you examine Kate Murphy's key, the tag with it says "Green Casino" instead of "Greene Casino".
  • In the "Table Games" crime scene, when you use the Instant Magnifier booster on the hat, the hat is shown to be white, but in the scene, the hat appears in black. It is most likely a developer oversight.
  • This case, Into the Vipers' Nest, and Under the Skin are the only cases in the game in which the murder weapon (in this case, Brooke Chase wanted the team to look at the samurai sword) is found by a suspect who opts to help you rather than by conventional police force findings.
  • In the crime scene "Trading Floor", there is a collectible object named "Creepy Girl". It is most likely a reference to Samara from the the 2002 American psychological horror film The Ring.
  • This case introduces two new forensic mini-games, as described in the following.
    • Reveal: Using forensic powder, the player will need to brush the item in order to reveal any hidden clues like fingerprints or text.
    • Find the Same: Using the police database, the player will have to pick the item matching the character's model for identification.
  • In the mobile version of this case, the murder weapon is revealed to be a katana rather than a samurai sword.
