This is the first official confirmation of the link between the two killings which happened after a gap of two years of each other.
M M Kalburgi, 77, was shot dead in his house on August 30, 2015, in Dharwad and Gauri Lankesh, 55, on September 5, 2017.
The bullets in both cases "have been fired through a single country made pistol chambered for 7.65 mm caliber pistol cartridges," a source told PTI quoting the report. The report also said the scratches formed by the firing pin on the bullets tallied among themselves.
Gauri Lankesh, who was also known for her strong anti-Hindutva stand, was shot dead in front of her house, triggering a nationwide outrage.
