Ether 15:31

And it came to pass that after he had smote off the head of Shiz, that Shiz raised upon his hands and fell; and after that he had struggled for breath, he died.

After he cut off Shiz’s head, Shiz lifted up on his hands and fell down. After he fought to breathe, he died.

After Coriantumr severed his head, Shiz’s body raised up on his hands, then fell. He struggled for breath, then died.
