Erin Hunter said this quote
“ Fireheart tensed, waiting for whatever had hunted down these apprentices to emerge from the trees and attack, but nothing stirred. Feeling as if his legs hardly belonged to him, he sprang down and stumbled across to Swiftpaw.The apprentice lay on his side, his legs splayed out. His black-and-white fur was torn, and his body was covered with dreadful wounds, ripped by teeth far bigger than any cat's. His jaws still snarled and his eyes glared. He was dead, and Fireheart could see that he had died fighting. ”
