It has never been proven who actually fired the final shot into his ear, or determined whether this shot was made during the gunfight or as part of a possible execution, with wide speculation remaining regarding the subject.
Det er aldrig blevet bevist, hvem der faktisk fyrede det endelige skud gennem hans øre, eller afgøre, om dette skud blev lavet under ildkampen eller som led i en mulig henrettelse, og der er stadig stor spekulation om emnet.
