Whether landlord should prove as per S 106 of the Evidence Act that who has murdered his tenant if he owned premises where the murder was committed?

Circumstance (a) - Re: Apartment from where the dead body was found stood in the tenancy and possession of Santosh.29. Insofar as tenancy of the apartment being with Santosh is concerned, the same has been proved by the testimonies of PW3 and PW4. Nothing material could come out from their cross-examination, nor any such suggestion has been given to them, as may cast a doubt on their deposition
