I don't even want to imagine listening to the meaty thunking sound of 50 plus stabs into that woman's body over 60 seconds of time.  

One meaty 'chk' every second---all in "self-defense"!

"In the recording, a woman’s prolonged shrieks and moans can be heard, along with a series of “chk”-like sounds, over the course of roughly one minute."

If I were on the jury, I would probably interpret those wounds and sounds as evidence of  a blind rage.
