I think that Mr.J.F.K wife (spies ) killed her , shes the Presidents Wife , she has so many connections so i think she sent out the secret service to kill her . Because she found out about there suppose affair ,but anyways they (her spies) , had put a nun-traceable drug in her pill bottle . & i suppose they knew Mrs.Monroe was depress and was taking meds cause there the secret service . So at the end that might be the case . & Do anyboody finds it creepy that his wife looked just like Mrs.Monroe just had black hair instead of blonde . But please correct me if you know or think im wrong but please dont be mean about it .
