Four suspects in the killing of a former member of the Tamil Eelam Police Department were found innocent and freed by a judge in Mannar, reported the Uthayan.
A total of seven suspects were arrested after the murder of 34 year old Naguleshwaran Krishnasuwamy, who was killed in his own backyard by unidentified gunmen in November.
His wife, Kavitha, said her husband had received threats in the days prior to the assassination.
Two unidentified men shouted the name of the victim in "an alarming tone", said Kavitha. When she told her late husband of the incident, she said he had replied saying, "I do not have any enemies or people who hate me".
An activist from an adjacent village, Thevanpitty, said the victim was engaged in encouraging Tamils to submit evidence to the UN inquiry into mass atrocities committed against the Tamil people.
Military intelligence officers had demanded that Mr Naguleshwaran provide information about non-rehabilitated LTTE cadres or supporters in the region, however, he refused, a local source said at the time of his killing.
Mr Naguleshwaran had previously served as a police officer in the LTTE's police department in the LTTE run defacto state of Tamil Eelam.
At the end of the armed conflict he was detained by the Sri Lankan military and put through the government's 'rehabilitation' programme for former LTTE cadres. In 2012, he was allowed to return to his family and given a daily wage for low skilled employment.
