PATNA, Jan. 16 -- The bodies of a 28-year-old woman and her three minor children were found on the bank of the Gandak river in Muzaffarpur district under mysterious circumstances, five days after they went missing, police said on Thursday. While police suspect it to be a case of suicide, the woman's husband has alleged that his wife and children were murdered elsewhere and their bodies dumped near the river. Following the recovery of the bodies, Muzaffarpur Senior Superintendent of Police (SSP) Kantesh Mishra constituted a Special Investigation Team (SIT) to probe the matter. "All four bodies were tied together and have been sent for postmortem. Only after the postmortem report is received will it be clear whether the deaths occurred due to drowning or if the bodies were thrown there after murder," the SSP said. Police identified the deceased as Mamta Kumari and her three children, aged between two and seven years, who had gone missing from their home in Bakhri Sipahpur under Ahiyapur police station limits on January 10. Mamta's husband, Krishna Mohan Kumar, an auto-rickshaw driver, had launched a search for them. Two days later, Kumar received a call from an anonymous number, during which the caller allegedly said, "We are going to marry each other. Don't try to find us." Following this, Kumar lodged a complaint with Ahiyapur police on January 12. Mamta and Krishna Mohan had married in 2019 and were living in a rented house owned by Amrendra Kumar Singh. The couple had three children, including two sons. Upon receiving information about the recovery of the bodies, the Muzaffarpur SSP, City SP, SDPO-II and a Forensic Science Laboratory (FSL) team reached the spot and initiated an investigation. According to Krishna Mohan, he had left home around 5 am on January 10 to drive his auto. "When I returned around 6 pm, my mother told me that Mamta had gone to Zero Mile for shopping with the children around 11 am but had not returned," he said. He further claimed that the family received calls from two unknown numbers around 3 am on January 12, during which the callers threatened to kill the entire family if police were informed. The family alleged that despite repeated information, police failed to take concrete action, which ultimately led to the killing of Mamta and her children and the dumping of their bodies into the river. "The matter is under investigation. Police will analyse the call detail records (CDR) of the anonymous callers to identify them. We will also correlate the FSL and postmortem reports to ascertain the cause of death," SSP Mishra said....
