Who killed Ashfur?

It is confirmed in Sunrise that Hollyleaf killed Ashfur. Before she ran into the tunnels, Hollyleaf told Jayfeather and Lionblaze that she killed Ashfur. Also, when Leafpool was preparing Ashfur's body for vigil, she said she found tufts of Hollyleafs fur in his claws. Earlier, Leafpool revealed to Hollyleaf that she knew of her crime--the same conversation in which she told Hollyleaf that she (Leafpool) was her mother.

Evidence leading up to the revelation:

• In the Prologue to Sunrise, Leafpool found tufts of black fur in Ashfur's claws.
• After Ashfur died, Hollyleaf acted very guilty--not eating and going around with a haunted look.

Swiftfire speaks:

Well, I wouldn't want Hollyleaf in StarClan since she killed Ashfur and literally ruined Leafpool's life. She should be in the dark forest with Tigerstar D:

moonstar Speaks:

I agree with swiftfire.now leafpool has to be a warrior.Now leafpool has nothing not a mate, her other 2 kits hate her now and squirrelflight lost her mate also.
