‘Skin-hunting’ is a term coined by Polish journalists to name a specific system of corruption that came to light in 2002 in the third largest city in Poland – Łódź. The activity involved an ambulance crew which would tip off a certain funeral parlour about ‘new skins’ (recently deceased bodies), and help to arrange funeral plans with the corrupted undertaker. The involved paramedics also admitted to kill a number of elderly patients using a muscle relaxant, Pavulon, in order to increase their necrobusiness profit. Although discovered in 2002, it is believed that the practice could have started in the early 1990s.
Here is a documentary, produced in 2008 and available in English, that interestingly illustrates the context of the crime.
