Murder accused Sonam left behind something which the Meghalaya Police found while searching the room of a homestay where the Indore couple stayed. This object gave the police investigation a big hint in which direction the case would go. Before the couple left the homestay, she left her mangalsutra and a ring in the room, Deputy Inspector General DNR Marak told NDTV. "In the room of the homestay, we found Sonam's mangalsutra and a ring in the suitcase, which gave us the first doubt. Why would a woman who recently got married leave her mangalsutra in a suitcase during their honeymoon?" Mr Marak said, referring to the ornament that symbolises marriage. Sonam's husband Raja Raghuvanshi was allegedly murdered by her and three contract killers while the couple was on a honeymoon. Another accused and Indore resident, Raj Kushwaha, has been named as her lover who helped in plotting the killing. "We did a very thorough, detailed investigation and the accused have admitted to their involvement," the police officer said.
