MM Kalburgi was a Sahitya Akademi award-winning writer of old Kannada literature.New Delhi: The Supreme Court on Tuesday transferred the investigation into the killing of scholar and rationalist MM Kalburgi to the SIT (Special Investigative Team) investigating the murder case of journalist-activist Gauri Lankesh after Karnataka government said there were common links in the two cases.Kalburgi, a former vice-chancellor of Hampi University and well-known epigraphist, was shot dead at his residence in Kalyan Nagar in Dharwad in Karnataka, on August 30, 2015.Born in 1938, he was a Sahitya Akademi award-winning writer of old Kannada literature.The state Crime Investigation Department was probing Kalburgi's killing and the Special Investigative Team was investigating the murder of Gauri Lankesh in September 2017 in Bengaluru.During the hearing, the top court said the SIT probe into Kalburgi's killing will be monitored by the Dharwad bench of the Karnataka High Court.A bench of justices RF Nariman and Vineet Saran said if killings of Kalburgi, Ms Lankesh and social activist Govind Pansare and rationalist Narendra Dabholkar are linked, it should be probed by one agency and monitored by one high court.Advocate Devadatt Kamat, appearing for Karnataka government, said there is already a Special Investigative Team investigating  the Gauri Lankesh case, while a Maharashtra Special Investigation Team was probing the killing of Govind Pansare in 2015.He said the Central Bureau of Investigation (CBI) was probing Narendra  Dabholkar's killing on August 20, 2013.The top court's order came on a plea by Kalburgi's wife, who had alleged that there was a common link between the murder of her husband and that of Dabholkar and Pansare, and hence the probe should be done by the CBI.On January 25, the top court had termed the plea "very serious case".On December 11 last year, the court had favoured a CBI probe into the murders of Kalburgi, Pansare and Lankesh, if there appeared any "common thread" in these incidents.The killings of all these three activists happened within a period of five years.The top court had asked the CBI to inform it whether it would like to investigate these three murder cases as it is already probing the killing of Narendra Dabholkar.Karnataka police in its status report had told the top court that there appears to be an "intimate connection" between the killings of Kalburgi in 2015 and Gauri Lankesh in 2017.The court had observed that one probe agency should investigate all the four cases if prima facie it appears that there is a "common thread" in the murders.The top court on November 26 last year had pulled up Karnataka government for "doing nothing and just fooling around" with the investigation and indicated it may transfer the case to the Bombay High Court.The top court on January 10 last year had sought the response of probe agencies NIA (National Investigation Agency) and CBI and the two state governments on the allegation of Uma Devi that no substantial investigation has been carried out so far in the murder case.
