In September last year, the Supreme Court had reduced Govindachamy's sentence to 14 years in jail, saying there was not enough evidence that 23-year-old Soumya had been murdered or pushed off the train.
However, the doctor who had examined Soumya's wounded body has said that there was no doubt her death was murder, not an accident. "The victim was in no condition to even escape or react after six severe head injuries were inflicted on her," Shirley Vasu had told NDTV.
Govindachamy also jumped off the train after her, hit her with a stone and raped her. Soumya died five days later.
