|Abandoned Crime Scene|
Within the warehouses of the Violence District, a chalk outline of a body, and a blood spatter can be found.
Due to its close proximity to the Gunman, it's possible that this is the scene of one of his prior shootings. What lends verisimilitude to this assumption is that occasionally, when the Gunman is approached in his warehouse, he shoots another person before turning around to shoot you. So, it's a reasonable conclusion to come to that this is another of his victims.
