I attacked opponent with more than fatal damage, they didn't block and their life total went negative (-5). They did not die despite neither player having any effect that would cause this. I attacked again in the two turn I had after this, both times dropping their life total further negative (-14ish, -20something). After this, they attacked me for fatal, and I died after my life total dropping to negative.
