A 16-year-old, named as Jan D. and 22-year-old, Hendrik M., from Rottenburg in Baden-Württemberg, are accused of killing the 39-year-old taxi driver in Prague in June 2013.
The killing of the father-of-three, whose girlfriend was pregnant, was carried out in front of a Prague cemetery. The victim was killed with 42 blows from a wrench and a hatchet.
According to Bild newspaper the older alleged murderer thought he was the evil witch Bellatrix Lestrange from the Harry Potter books.
And prosecutors said the murder was committed out of satanic “bloodlust”.
In a statement they said: “Both accused had a keen interest in Satanism and Vampirism.”
They added they took an interest in satanic music as well as books and films about Satanism with “very violent elements”.
The two are also accused of attempting to murder a driver at a vineyard in Metzingen, Baden Württemberg, in spring 2013.
A verdict is expected on May 27th.
