Body Count

The article states that this version of Joker has a body count of between 19 and 30 people, but to my memory, I can only think of one time when the Joker actually seemed to kill anyone and that was in The Batman vs Dracula, in which a vampire-ised Joker attacked Gotham City Blood Bank and it certainly looked like he killed the receptionist. Can someone please tell me where this figure came from?
