It is the family of Dr. Talwar that asked for CBI inquiry. Now why are they pushing for his bail? what are they afraid of? No police and investigative agencies will kill him like that when it is under media scanner. Any person who is not guilty will not the afraid of anything. In fact it looks like, Talwar's were planning to buy police by bribing them and cover up the case. In fact they may have been successful initially. That is why police have not collected finger prints and brought dog squad for help. But when the story has become more than local and under the scrutiny of public via media, they have started blaming police for bungling. Had police handled this case professionally without getting influenced by Talwar' social standing and their closeness to people of power, this could have been solved much more earlier.
