Casper the deadly ghost

Because of two recent, though separate, suicides, Mrs. Farrell's tenement house was considered to be haunted. In fact only one family remained in the building everyone else moved out. Twas 6:30 in the evening on this date back in 1927 when Mrs. Farrell ascended the staircase in her task of lighting the hallway lights.

When she got to the top floor she tripped over something. That something turned out to be a man, judging by appearances, of Italian descent, about forty years old. Mrs. Farrell barrelled down the stairs and got the police.

The corpse had no identification but he did have bullets in the head, shoulder and leg. He had a gun in his pocket and two more were found on the floor near him. One missing the three bullets that now rested in the dead man. The walls and a door showed evidence of another gun being fired. Oddly, Mrs. Farrell had heard nothing. The one remaining family in the building also had heard nothing.

So we have a dead guy, who didn't live in the building, a victim of a gunfight that nobody heard. The police went next door and began to ask questions. Turns out that the woman who lived in the adjoining apartment heard a little something that morning at 10:30. That something sounded like a struggle followed by a guy yelling, "Oh my God don't! Oh my God!" followed by a number of gun shots then silence.

When asked why she didn't report anything she said she was afraid the killers would come for her. Police chalked the murder up to a bootleggers feud. But having seen one or two shows on the paranormal I think it's fairly obvious that this was the working of one pissed off incubus, or is it succubus or omnibus...well one of the buses did it anyways I'm sure.
