Bathinda, May 21 -- Two months after the body of a 19-year-old college student was retrieved from a canal near her hometown (Maur) in Bathinda, investigators say there is no clinching evidence to prove it a murder or that the victim was subjected to sexual abuse. The police are yet to submit a chargesheet in the court. Officials familiar with the probe said on Tuesday there were digital evidences that the victim boarded a private bus in Chandigarh after leaving her college hostel to reach Maur on March 9. "The probe is almost complete and a special investigation team is relying upon the chemical analysis that did not mention rape. The forensic probe has not found any injury mark on the body, ruling out physical assault," said an official requesting anonymity. Sources said that main accused Mukul Mittal was in a relationship with the victim. After reaching Maur, the victim and the accused reached near the canal in which she fell under suspicious circumstances. Sources said the forensic report mentioned drowning as the cause of death but officials say the SIT has not come across an eyewitness or material evidence to prove that she was thrown into the canal. SSP Amneet Kondal said that the SIT is still investigating the matter and a chargesheet will be filed in the court soon. Six persons - main accused Mukul Mittal, his father Ravi Mittal, mother Dimple Mittal, uncle Raj Kumar Mittal, Mukul's friends Karan Bansal and Raghav Singla - were arrested in the case. The accused were charged with murder, kidnapping and criminal conspiracy based on a complaint filed by the aggrieved family. Police sources said Mittals were victim's neighbour and both families had good relations....
