I think the criminal element in the human village would be virtually non-existent. The population is too small and there aren't really any other places to go. It's the kind of situation where everyone knows everyone. Getting banished from the village is also a virtual death sentence.
Supposing this guy got away, what exactly is he going to do? With that being the case, maybe he believed he was entitled to the lady's property? Maybe he did something for her and she refused to pay, and he acted out?
We don't have all the facts, and even supposing we did take things at face value, feeding him to the local vampire lord is not a punishment that fits the crime.
