Everyone "A" Did (and Didn't) Kill in "Pretty Little Liars: Original Sin"

Did "A" Kill "Crazy Joe"?

The circumstances surrounding "Crazy Joe"'s death are a little murky. By all appearances, he dies by suicide after Imogen discovers him in the Waters's house, implicating him as a henchman for "A." The Liars later discover "Crazy Joe" dead in his train car/home, appearing to have hung himself. Still, Imogen and Tabby suspect that "A" may have staged his death.

Why Would "A" Kill "Crazy Joe"?

"Crazy Joe" was on Team "A," considering he purposely sent the Liars on a wild goose chase to throw them off the real "A"'s scent. He also left a suicide note that said "Angela Waters did not die in vain," suggesting his death was, in fact, by suicide. Still, as Imogen and Tabby suspect, it's possible "A" killed "Crazy Joe" as a cover, though their theory is never confirmed.
