YES,You are right. There is nothing wrong in taking compounder Krishna for further interrogations. After all his finger prints are available on one of those mysterious three glass left in servants room along with a whiskey bottle.
Noadays technology , I think can even detect how long the finger print had been there(the age of the finger printt). His hand print was also found on the AC vent in the room (aurishis' room)? It was also found that he was seen with Hemaraj the servant late in the night near wine shop on the night of murders. According to his own admission, it seems he had a heated argument with the servant(in servant room). During the night of murders while Dr.Talwar and his wife were sleeping, the compounder came in and again servant and compunder went out to a shop and came in again more than two times.
So far,it has been a mystery , as to who had entered the house without breaking the locks and now it has come to known that not once but several times such an entry without the knowledge of house owner happened !!
what if , the compunder is a poor begger? should not he be interrogated? who is that third murderer who it seems used the weapon.
It seems that even the servant who was also a victim , was aware or even present in the room when that 14 year old girl was killed in her own house. I believe that CBI would definitely solve this case.
