An analysis of the CCTV footage of the killing of Rajput leader and Karni Sena chief Sukhdev Singh Gogamedi in Rajasthan has found something that could have given a new tangent to investigators. But this tangent is no longer possible as the man involved also died in the shooting. One of the three shooters, identified as Naveen Singh Shekhawat, was killed in the crossfire. Police sources, however, said a closer look at the footage clearly indicated Shekhawat was on to something else - he apparently may have tried to prevent the shooting at the last minute.
