But Joker's wife died before giving birth, at least in The Killing Joke story that introduced the concept, so it'd make it a lot harder to connect those dots using them. Harder still to have the prescience to fake their deaths and witness protect them prior to him even becoming Joker, but I guess the cops could have caught wind of the robbery (they and Batman got there quickly).

Regardless, like most of Johns' Batman writing it was the absolute least interesting, most contrived and frustrating way the story could have gone in my opinion.
