I'm not sure it's about homicide, to be honest.

Someone mentioned Black Sheep Boy, one of their more... prominent albums, it seems.

In many of their songs, you hear of how a woman still loves a stone, especially in the Black Sheep Boy album. How she cannot be with the man (singing) because she's still in love with the man that died long ago. She's in love with a head stone and the guy singing just really wants to be with her.

Because someone died and she has blood on her, doesn't necessarily mean she's the murderer. He's asking her to come into his arms because she's upset. I'm suspecting this might be the original place where the girl's love dies.

But that's just my take.
