Hello! If Jackson's a forensic pathologist, he and Heiji might have run into each other :). He's not a policeman, of course, being a fae, but he does work with the police on occasion.

Also if you want to work anything into the vampire plot, let me know. Some of the minions have Carmilla's sigil on their clothing, for instance, which might help someone with the right resources figure out who it is ahead of time.
