Answer 2

Thanks for the very interesting question.
For these type of questions , sometimes the answer is in question itself :)

The question asked is "Who was murdered" 
The answer to this is A man was murdererd!

Regarding to who murdered the man! The answer could be Maid murdered the man as she is speaking a lie that she was getting the post. As Post office doesn't work on Sunday; so she is lying and could be a murderer.
