Try it : Who was the murderer ?

An old man RAM lives alone in a flat. Because of his age , he is not able to move comfortably and hence most of the things used to be delivered to his house. On Friday while delivering the mail , postman feels something suspicious in the flat and try to look inside through the key hole and he saw a blood filled body of the old man. CID arrived the scene. On the outside of flat , he found two bottles of warm milk , Tuesday newspaper, some unopened mails , some gifts. CID waste no time to find the murderer.


Who was the murderer ?
Your problem isn't the problem. Your reaction is the problem.
I think, The person who delivers newspaper is the murder as newspaper after Tuesday was not delivered.
"Literary education is of no value, if it is not able to build up a sound character"
My guess would be friend of old man as there was two bottles of warm milk ( one bottle of warm milk for him and another for his friend )
