On this page of the guide to Disco Elysium, you will find an accurate description of completing the Send victim's body to processing task.
In the task Send victim's body to processing in the game Disco Elysium, the dead man's body should be sent back from the scene.
After the autopsy is completed, you can send the body back, but before you do, make sure you've found all the traces and done all the side quests related to the body of a dead soldier.
- You've found a bullet in his skull: task Find the bullet before you get fooled ;
- You got his footwear: task Getting the Hanged Man's boots. Getting the boots off the body also accomplishes a part of the task Find all armour pieces.
Once the body is sent back, there will be no way to bring it back. It should also be marked by the fact that Kim will take care of this personally and so he will not be there for you for the rest of the day.
