What is the Joker's alter-ego?

Well now we can take the Joker story wife thing as real.

Joker found out that his wife was knockoff to force him in the crime.

Joker found out the cop that killed his wife(A dirty cop at that.)

But do not know if the Joker killed him yet or Batman saved the cop. I hope the Joker does kill him, the problem in this story though is well, The Joker is too sane for my taste. lol
