Look for exsanguination, the expected bite marks, injuries to the victim consistent with an assailant of inhuman strength. Also be aware that the victims may reanaimate suddenly, and may be in a feeding frenzy. I believe there to be more than one type of vampires here. Also more than one type of wereanimal. My sense of smell tells me that.
