Who's guilty?

(Deep narrating voice.) It was an ordinary morning, I went to get a coffee at the cafe, when I heard a scream. A damsel's scream to be specific. I knew it was a case. For I am a Private Eye.
I immediately started looking for clues. When I stumbled upon one.

They seemed to be some footprints. Made by flour. To small to be a teenage boy ones. Perfect for little girls....

Then I found the victim. Limp, dead.

I examined her, I found the wound.

(Normal voice.) All clean!!!!
