The Goa police believe that the 39-year-old Suchana Seth might have sedated her son with cough syrup before executing the crime, indicating that it might be a pre-planned murder.
A senior police officer told PTI news agency on Tuesday that a cleaning staff found two empty bottles—a small and a large bottle—of cough syrup in her at Goa's Candolim.
Police say that Seth might have given a heavy dose of cough syrup to the child, and then smothered to him death either using a cloth or a pillow.
"The post-mortem conducted on the body has indicated the possibility that the child might have been smothered to death and there were no signs of struggle," the unnamed cop told PTI.
"We are examining the possibility if the woman gave a heavy dose of cough syrup to the child before putting him to death," the official added.
During their inquriy with the service apartment staff, the cops found that the woman had asked them to buy a small bottle of cough syrup, claiming that she was having a cough. The cop said that the bigger bottle might have been carried by her.
"It looks like a pre-planned murder," the officer was quoted as saying.
The cop's assertions contradict Seth's statements who, during her interrogation, reportedly claimed that her son died during his sleep and that she did not know how her son died.
"We don't buy her theory. Further investigation will reveal the motive behind killing the child. As of now, we know that she and her husband were estranged because of which she might have done this," another senior police officer told PTI.
Seth, the chief executive officer (CEO) of an artificial intelligence start-up, was CAUGHT in Karnataka's Chitradurga region on Monday night while she was on her way to Bengaluru. The boy's body was found in a luggage.
