"People walk differently when they're rushed or when they're anxious or when they're scared. Their feet hit the ground differently. For more or less time, at different angles. There was so much blood on his shoes that you could see his footprints perfectly. I'd guess that the damage to the victim was done with a blade. You can kill someone by exsanguination with a projectile or even... manually. But for efficiency? You really can't bleed a person like you can with a knife or a razor or... something of that ilk," he assures them. "And I'd guess we're dealing with a cut artery for the blood to all be in one place. If someone was injured badly but bleeding out more slowly than that, they would try to escape. Crawl to the stairs. But, again, the footprints suggest pooling rather than a spread. That being said, arteries spray. The person doing the clean up... was thorough. We didn't find so much as a drop of spatter on our side of the gate."
