Is There a Pattern of Blood in the Middle of a Pillow?

Police are speculating that the odd shape of the pattern of this blood is pretty specific to a kind of a pointy weapon. "I don't see anything that I would characterize as a specific pattern," he says. The coroner did say she was killed sometime between 3 a.m. and 4.45 a.m., but police didn't get there until like 6.02 a.m,. So that's so much blood.
