Wow. This is scary. I have several thoughts:
1. The wording you used in the original post -- is that EXACTLY what the note said? Exact wording, exact spelling? If so, it's incredibly mature language for an elementary school child. My oldest daughter, at that age, was testing waaaaay above elementary school age, and she still wouldn't have chosen that wording. Certainly it's "borrowed" from some game or book. That makes me suspect an adult's involved. You said that the writing was childish; perhaps it's an adult writing with the left hand to disguise the writing.
2. Or, perhaps the notes are coming from a child who has an older sibling; the sibling could be helping with the note writing at home. The note seems -- to me -- to scream lonely, misfit, intelligent teenaged boy. The type who has read every one of the Lord of the Rings trilogy five times, the type who can quote every line of the Matrix movies, the type who sees himself as really cool but who sits alone in the cafeteria. I can imagine a 4th grader coming home saying, "I don't like this girl in my class", and the older sibling saying, "I know how we'll get her."
3. The last note -- the you will die note -- doesn't fit. The first notes were wordy and poetic in a disturbing, gothic style. The very simple wording in the death note seems very different. That makes me suspect that a copycat wrote the last one. Or, if my sibling theory is correct, it could be that the child wrote the last note without the older sibling's help.
4. Another poster said that the school would downplay this type of thing -- absolutely not. If something really does happen to the child, the school will want to be able to prove that they did everything possible to protect the child. Of course they're not going to go on loudspeaker and announce, "Whoever did this had better quit" -- that would be the same as inviting everyone who owns a pencil and paper to start writing similar notes next week! The school will aim for secrecy AND protection.
I don't know about elementary schools, but our middle and high schools all have a Resource Officer who IS a member of the local police force. He's the person to whom these things should be reported. Through him, the report will go to the city/county police department. When things like this rear their ugly heads, the first thing our principal does is go to the Resource Officer -- these are legal matters, so he's the appropriate person.
5. I think moving the backpack was a dumb choice. Sure, it'll prevent more notes from coming home, and that'll help the child -- and parents -- feel better. But a smarter move would've been to set up a camera (those nanny cams are inexpensive and available at Radio Shack) and try to catch the culprit. Unless it's the classroom teacher (unlikely), they probably would've caught the note-writer sneaking in at lunchtime, recess time, or something like that.
6. I don't think I agree with the "keep her home from school" idea. It'll add fuel to the fire and scare her more. Instead, I think I'd go with her to school. I would see her into the classroom, then go work in the library or the office. Of course, I'd know what time the class was leaving for music, etc. and I'd just happen to be in the hallway at that time.
Plus -- and this is a horrible thing to say -- if someone has specifically targeted her for some reason and is seriously going to do something, they'll do it at home instead of school. At least at school other people will be around, and they will be there to help her.
7. Why her? Do you have any clue? Does she stand out in any way? Is there another child who dislikes her?
8. Does she have grandparents / aunt and uncle locally? If so, I'd consider staying with them for a bit so that this note-writer doesn't know where you are.
This is really a terrifying example of how the world we live in can be so ugly. Please keep us updated. I'll pray for the child (and for justice for the criminal who's doing this).

for you and especially your daughter. 
. I am thinking good thoughts for you and your family to come through this safely. Please, please, please do everything you can to keep your baby safe. I don't think my little girl would be going to school tomorrow. 
OR, it could be that you are a professional and I am not....just an on-call aide or lunchroom help.
