Two Questions

Spoilers Ahead

I was wondering if anyone knows the name of a piece of music that was used in the film. When the priest goes to visit the older gay man he is giving a piano lesson to a young boy. Does anyone know the piano piece the child is playing?
Secondly, the killer is revealed to be the same person who strangled a girl years earlier. What was the reason the girl was strangled years before? As far as I can tell this was not explained.


i cannot answer your first question,
nor can i answer the second, but i am wondering the same as you
