KJ Singh, a journalist based out of Punjab and his mother were found dead in their house in Mohali on Saturday.
"There was injury marks on their necks," Mohali deputy superintendent of police (DSP) Alam Vijay Singh said. The investigations are on.
Mohali senior superintendent police Kuldeep Chahal confirmed the double murder in Phase 3B2 and said the motive was being investigated.
Singh was in his sixties while his mother Gurcharan Kaur was 92 years old.
Police sources told Hindustan Times that Singh was found with his throat slit, while his mother, Gurcharan Kaur, is believed to have been strangled. The police also said that the journalist's car is missing.
Singh was a former news editor of the Indian Express, The Tribune and The Times of India in Chandigarh.
In what is said to be a co-incidence, Singh is the third journalist to be killed in India within days of the murder of Gauri Lankesh, a Kannada journalist, and Shantanu Bhowmik, who was killed in Tripura earlier this week.
"I condemn ghastly murder of senior journalist KJ Singh and his mother at Mohali. Urge police to nab perpetrators immediately," tweeted senior Akali Dal leader Sukhbir Singh Badal.
The Punjab Police has set up a Special Investigation Team (SIT) to probe the murder case.
