Source for the conviction by the NKVD for attempting to assassinate Stalin?

edit

I was editing this and cleaning it up a bit, and went through the sources. I couldn't find anywhere that said he was convicted for this nor that he was tortured for months. The only source I could find that still works says he was arrested when the church was discovered following which he was executed and his monks were sent to prison camps.
