Can you tell me who really killed John F Kennedy and don't say Lee Harvey Oswald?

It is widely accepted that Lee Harvey Oswald was the sole perpetrator of the assassination of John F Kennedy, but there is evidence to suggest that Oswald may not have acted alone. A number of conspiracy theories have been proposed which posit other groups or individuals as participating in the crime.
