On this page you’ll find information about solving the Crime Scene in morgue at the Gotham City Police Department during 1.2 - The Langstrom Drive.
As you attempt to solve Cases (read: quests), you’ll occasionally have to investigate Crime Scenes. This involves scanning various objects by highlighting them with the to gain additional information about them. Once you’ve studied all the objects at a particular crime scene you’ll have to solve a puzzle, usually by matching various crime scene points of interest together by using the information gathered to infer which ones are logically connected. This is done by highlighting one category of object and selecting it by pressing / , then highlighting and selecting other categories of object. If all else fails, you can blindly guess until you match the correct objects, but with this guide you shouldn’t have to!
After you bypass the cameras and snatch the sergeant’s keycard you’ll head to the morgue, where, after a scene, you’ll find yourself examining a body. Your goal this time is to find a biodecryption key, which involves scanning more objects, including several devices that may possibly conceal the biodecryption key (a blood glucometer, Langstrom’s phone, an MMO key fob and a pulse oximeter) and possible samples used with the biodecryption key (blood vials, soft tissue samples, urine samples):
Which Devices Might Conceal the Biodecryption Key?
- Blood Glucometer
- Langstrom’s Phone
- MMO Key Fob
- Pulse Oximeter
What is Sample Required to Use the Biodecryption Key?
- Blood Vial
- Soft Tissue Samples
- Urine Samples
How to Find the Biodecryption Key
This one’s pretty easy, simply because most of the potential devices concealing the biodecryption key have no good way of interfacing with any of the biological samples. The blood glucometer and the pulse oximeter are really the only two that have any potential medical purpose, and the blood vial, soft tissue samples and urine samples have no good way to interface with the pulse oximeter.
You can confirm your suspicions further by examining various clues: the “medical bracelet” informs us that Langstrom wasn’t exactly in rude health, while his wallet - full of guilty fast food loyalty cards - isn’t the sort of thing you’d expect to find on a diabetic. The pulse oximeter likely had a genuine healthcare function, but the blood glucometer is both superfluous and it interfaces with the blood vials.
Select the blood glucometer (highlight it and press the / button), then do the same for the blood vials and you’ll get your biodecryption key.
