Senior journalist KJ Singh and his aged mother were found dead in their residence in Mohali town in Punjab, adjoining Chandigarh, on Saturday, police said.
Both victims were attacked by their assailants with a sharp-edged weapon in their house in Phase 3B2 of Mohali, 10 km from Chandigarh.
Police said that Singh's mother, Gurcharan Kaur, (89), was strangulated.
Singh was stabbed in the stomach and his throat was also slit.
The bodies of the victims were discovered on Saturday afternoon when a maid came to the house but no one answered the bell.
Police sources said that the murder could have taken place around 1 am on Saturday.
The house was found ransacked and some items were missing.
Singh's car was also taken away by the assailants.
Singh, a bachelor, had remained Chief News Editor of The Tribune. He was earlier News Editor with the Times of India and had been with the Indian Express previously.
This also comes less than a week after a news reporter for a local channel, Shantanu Bhowmick, was abducted and hacked to death while covering the clashes that broke out between the CPI-M's tribal wing Tripura Rajya Upajati Ganamukti Parishad workers and the cadres of the Indigenous People's Front of Tripura, a tribal-based opposition party, in Tripura.
Following the murder, journalists descended on the Press Club of India in New Delhi and demanded action from both the state and central governments into the life lost in the line of duty.
To make their protest more symbolical, the fraternity decided to carry out a silent march on October 2, Gandhi Jayanti, to the Home Ministry and present there a memorandum of their demands.
