this sounded all right to me, you can always capo it or transpose or whatever to the key 
you want to sing at, i'm not really sure if this is in the normal key, but yeah.

Intro/verse: Dm F C Bb (its the same through the whole song)

Hits when I'm asleep right through
I'm cold when I wake cause I won't feel you
When I can't breathe I know it's you
Got a lump in my throat just thinking of you

Makes no difference you've been tried
(Makes no difference you've been tried)
Still sick inside, oh oh
It's meant to be over now
But I think we're going down (we're going down)

Got your fingerprints as evidence all on my body
Put your right hand on the book and you were found guilty
I can't wait forever but that's how it's gonna be
For me they'll never be

Case closed
No matter what the verdict say
Case closed
Too many questions in my head
Case closed
And I'm still waiting for a while
Why there can never be
Case closed

Behind these walls, so tall
I don't wanna climb, I'm afraid to fall
So we both do time and never have closure cause I still wanna hold ya

Makes no difference you've been tried
(Makes no difference you've been tried)
Still sick inside, oh oh
It's meant to be over now
But I think we're going down (we're going down)

Got your fingerprints as evidence all on my body
Put your right hand on the book and you were found guilty
I can't wait forever but that's how it's gonna be
For me they'll never be

Case closed
No matter what the verdict say
Case closed
Too many questions in my head
Case closed
And I'm still waiting for a while
Why there can never be

(-not sure of the chords here...the song doesnt really have any music)
They can never, never be a
Never be a
Never, never be a
Case closed

They can never, never be a
Never, be a
Never, never be a
Case closed

(Dm F C Bb)
Got your fingerprints as evidence all on my body
Put your right hand on the book and you were found guilty
I can't wait forever but that's how it's gonna be
For me they'll never be

Case closed
No matter what the verdict say
Case closed
Too many questions in my head
Case closed
And I'm still waiting for a while
Why there can never be

Case closed
