Got a work order for a water stain on the living room ceiling of an older lady's apartment. I knew there was absolutely no plumbing there, and the ceiling of her place was concrete slabs separating her place from the apartment above. I ring the doorbell for the apartment upstairs, no answer so I go in and of course yell, "Maintenance!". No answer. I did notice that there was about a week's worth of mail on the floor (The doors had mailbox slots). So I go in and walk up the stairs and as soon as I was eye level with the floor, the heat wave and stench hit me. I continued on up and sure enough, the resident was dead in his chair, his apartment was about 80 degrees so he was partially bloated, and his blood was seeping down between the concrete slabs of his floor... hand hanging above the dropped gun.
