 Another possible killer, Ella. If any of you have seen the gameplay of the second Danganronpa game, then you'd know when a certain innocent character was inflicted by despair and went for the kill. And since the pink bow is one of the clues, no other person wears it but Staci and...Ella. Further evidence is the fact that there was a sack of sugar and a necklace.

 I'm going to suggest that someone broke into the confessional while Staci was in it, thus using the hammer. While it could be Rodney who would follow Amy's orders to murder, I don't think that Rodney would be able to climb on top of the roof without breaking it and if he did, there'd be no use for the hammer. The pink envelope suggests that either Ella, Katie or Sadie could have done the murder. Jasmine can be ruled out as she was probably trying to catch food for survival. And with that, I believe the killer is....Ella.
