It's been a month since 14-year-old Aarushi Talwar and Hemraj were found murdered in Noida. But despite some key arrests, the CBI or the police are nowhere close to cracking the case. Although, on Saturday, the CBI did hint at more arrests after Krishna who worked for the Talwars. The investigating agency spent the whole day on Saturday searching for fresh clues after an anonymous tip that the murder weapon might still be at the Talwars' residence.
