In the movie, "Fight Club," the protagonists steal human fat extracted from liposuction clinics to make soap, which they then sell. In this case, it's a bit more grisly. Yikes.

Peru arrests 'human fat killers'
Four people have been arrested in Peru on suspicion of killing dozens of people in order to sell their fat and tissue for cosmetic uses in Europe.
The gang allegedly targeted people on remote roads, luring them with fake job offers before killing them and extracting their fat.
The liquidised product fetched $15,000 (£9,000) a litre and police suspect it was sold on to companies in Europe.
