One of the loading screens arts used in the new Batman: The Enemy Within series clearly uses the image of a dying Andrei Karlov, a senior Russian diplomat who was assassinated last December in a Turkish art exhibition.

The loading art in question shows a vault door opened following a bank heist. Directly outside is a cropped image of Karlov, as seen above.

The original image and information regarding the assassination can be read here.

Gamers are speculating that the artist responsible for the image was in a time crunch and searched for something along the lines of 'dead body on floor' using a search engine. The mistake likely happened because the source image appears to be stock given the incredibly bright lighting of the museum.
