Who killed Jay Gatsby in The Great Gatsby?

Wilson shotwhile
he was swimming in his pool.  Wilson suspects Gatsby of killing his late wife, Myrtle, because
he recognized the car model from the scene of the crime.  However, Wilson doesn't realize that
Gatsby wasn't driving; instead, it wasdriving, and Gatsby mentions tothat he knows Daisy meant
to kill Myrtle.  This is likely due to the fact that she knows her husband, , has been having an
open affair with Myrtle.  Rather than allowing Myrtle to get caught for murder, Gatsby is
willing to take the blame for the crime, proving just how much he loves her, despite the fact
that Daisy more or less used him just to make Tom jealous of her for having an
affair.
