Crime Scene Cleaners what is the most f***ed up thing you've seen on the job?

Obligatory 'not me but....' One previous time this question was asked someone reported they were cleaning a hotel room that had been used for an orgy. There's the mess you kinda expect in a situation like that - gross enough but just at the 'wreck your day' level not the 'wreck your month' level. But there's something HORRIBLY WRONG. There's a smell of death. These sick fucks got some live cats and placed them between the two mattresses (one was on top of the other), then sewed them together, then had the orgy on top while the cats suffocated and were crushed.
