Why Aren't You Dead yet?

Forensics of my heart
Show this crime scene has gone cold
But this new evidence uncovered
Will tell your secrets.
You are my chosen one
My perfect partner in crime
I had your back, you stabbed mine
Didn't see it coming

You never know you want it
Until you have to beg
You think that I'd forgotten
But here we are again
And nothing's changed, you haven't changed
You're still the same
Why aren't you dead yet?

Corroborate your alibi
Witnesses testified
That you were the guilty party
How do you plead now?
I am the innocent
But if thoughts could prove intent
And if I could get away with murder
You wouldn't last a day

Nothing's changed, you haven't changed
You wiped the scene and walked away
And did you think you'd ever get away with it?
Causing suffering and pain
Why aren't you dead yet?
