New York, Oct 12 : A Purdue University student, who allegedly stabbed his Indian-origin roommate to death on October 6, told reporters he had been "blackmailed" when asked about a motive for the crime. Ji Min Sha, a 22-year-old junior cybersecurity major from Seoul, made his first court appearance last week before Tippecanoe County Magistrate Sarah Wyatt after being arrested for allegedly killing Varun Manish Chheda, a 20 year-old studying data science at the university in West Lafayette, Indiana. "I was blackmailed," the suspect was reported as saying in the New York Post, But he didn't elaborate much on his statement. When asked by reporters if he had anything to say to the victim's family, Sha replied: "I am very sorry." Wyatt granted Tippecanoe County Deputy Prosecutor Timothy Kern's motion for a 72-hour continuance. Prosecutors have until Thursday to file the charges against Sha, who had said "I love my family" as he was hauled to jail for allegedly killing Chheda. The Indian-American student died of "multiple sharp force traumatic injuries" and the manner of death was a homicide. Purdue Police Chief Lesley Wiete called the crime "unprovoked and senseless". The suspect allegedly admitted that the knife was his and that he had used it to kill his roommate, the New York Post said. India, calling the incident unfortunate, said that it is keeping an eye on developments of the case. "It's a very unfortunate incident. I think the perpetrator has been arrested. We are keeping an eye on the developments," Ministry of External Affairs spokesperson Arindam Bagchi said during a press briefing. Meanwhile, several members of the Purdue community came forward to set up GoFundMe pages to help Chheda's family cover funeral costs, but his family has asked people to contribute to Riley Children's Foundation instead. Varun's grandfather Nemji Chheda had migrated to the US in 1964 from Kundrodi in Gujarat's Kutch district. According to media reports, he was the third generation of a Gujarati family that had moved to the US six decades ago. /IANS
