Khooni Bhavishyavani - S1.E668

CID reaches a mall where a man was found dead. The owner of the mall informs ACP Pradyuman that he whispered something in his ear before he died. Upon being asked he tells the team that the man said he is going to kill someone tonight at 11 P.M. How can one person who is already dead kill someone else? If he was going to kill someone who killed him?
