THIS is the story of a manhunt. Dara Singh, the prime accused in the Man-oharpur killings, is one of the most wanted men in the country today. The CBI, which took over the case in February, the Orissa Crime Branch and the state police have launched a search for the elusive killer who carries a reward of Rs 1 lakh on his head. After the gruesome murder of Australian missionary Graham Staines and his two minor sons, Dara has gone into hiding and despite all efforts, the police have failed to nab him. This despite four squads being specially constituted to comb the area where Dara has his hideout.
