Dave Taylor / Davey Herold Question

I am only guessing here, but Powell was trained in hand-to-hand combat and going for the jugular, which has virtually no protective skeleton around it, makes for a quick kill. The neck is also usually semi-exposed at least, whereas, in Seward's case, clothing and bed coverings add extra layers to cut through -- as well as having to make sure the blade hits between the ribs so that it gets to the heart.
