Amateur Exorcism in Romania

[Pricolici]

In 2004, Mircea Mitrica and five others were put on trial for digging up the corpse of a neighbour and removing his heart in Oltenia, Romania

Their defence?

It was part of an exorcism, to save the life of a possessed girl

Mitrica and others talk about myth, ritual and the tea of the human heart in Romania

This case sounds like it might have some connection to such beliefs.
