i don't know of any detective animes with vampires, but i know some with demons(they're close-ish, i guess?). i know an anime with a demon detective and a human partner, though to the public it's the other way around because the demon doesn't want to attract too much attention. it's called majin tantei nougami neuro. it's really good. sorry...
There are many different animes with yanderes characters. Some of the famous ones include Hikurishi, Elfen Lied, and Higurashi no Nuko. You can try these out and see if they captivate you.
