Journalist KJ Singh and his mother were found murdered at their house in Mohali on Saturday. The Punjab Police have set up a Special Investigation Team to look into their deaths, on Chief Minister Amarinder Singh’s order.

Singh, who was in his sixties, and his mother, 92-year-old Gurcharan Kaur, lived in Phase 3B2 in Mohali’s SAS Nagar. Police suspect that the double murder took place on Friday night. Their maid found their bodies on Saturday afternoon and alerted their neighbours, who then called the police.

Singh was found with his throat slit and his mother is believed to have been strangulated, the official spokesperson for the Chief Minister’s Office told PTI. Mohali Deputy Superintendent of Police Alam Vijay Singh said there were injury marks on their necks.

The police are looking into the motive behind the killings, which is unclear so far. Officers found the house ransacked. Their Ford Ikon car, television and a few other items are missing from the house, according to The Tribune.

Singh was a former news editor at The Indian Express. He had also worked with The Times of India and The Tribune in Chandigarh.

He is the third journalist to be murdered this month, after Guari Lankesh’s murder in Bengaluru on September 5 and Shantanu Bhowmik’s killing in Tripura’s Mandai block on September 20.

Former Punjab Deputy Chief Minister Sukhbir Singh Badal condemned the “ghastly murder” and urged authorities to arrest the perpetrators post-haste.
