The jury in the trial of two boys for the murder of 14-year-old Ana Kriégel has been shown a copybook belonging to one of the boys containing a reference to a “satanic pledge”.

When Boy B was arrested on suspicion of the murder of Ana in July of last year, he told gardaí that he knew about the copybook they had taken during a search of his home.

Boy B told them that in the copybook was the “satanist” cult. He said he called it that as he did not want certain people to join and he described it as a homework club.

Prosecuting counsel, Brendan Grehan, said there was a drawing of what was entitled “satanic pledge”. It was described as a drawing of a circle with a star shaped symbol in the bottom corner of the page.

On the next pages there were a number of circles with what looked like five-pointed stars or two triangles upside down. Mr Grehan said the stars might be called “a pentagram”.
