INDORE: A phone call between Sonam Raghuvanshi (in pic) and her mother-in-law on the day of Raja Raghuvanshi’s murder has become a chilling focus of the police investigation – was Raja already dead by then, or worse, was he being led to his death while Sonam calmly spoke to his family?.ACP Poonamchand Yadav told TOI that the sequence of events shared by the accused times the murder soon after that call. “That one call haunts us,” he said. “We now know from interrogations that the murder happened shortly after that phone conversation.” The call was placed when the couple was reported to be on their way up after visiting a double-decker bridge in Shillong’s Nongrait village. Sonam told her mother-in-law, Uma Raghuvanshi, that she would not break her ‘Gyaras’ fast just because they were away.When Uma called and asked her to connect with her son, Sonam replied sweetly, “Raja is walking ahead… his phone is in the bag, I’ll get him to call you later.” She was panting and so Uma disconnected the call.“That was the last time we ever tried to talk to her,” Uma said, her voice trembling. “I could never have imagined that the daughter-in-law, speaking so gently on the phone, was actually scouting for a spot to kill my son – perhaps even moments away from doing it.” Police are now analyzing call duration, location, and voice tone in what they describe as a “cold-blooded calm before the kill.”
