According to the CBI's report, no marks of violence were found on the exhumed bodies of the victims, Neelofar and her sister-in-law Aasiya, who were allegedly raped and murdered by security forces in May 2009.
However, some newspapers in Srinagar reported that the central probe team has concluded that the women died of drowning and there was no foul play in the deaths.
The drowning theory corroborates the first statement of Chief Minister Omar Abdullah on the incident.
He later said he had been misled by the Shopian district administration and police.
The Shopian incident had sparked off an agitation across Kashmir. Protesters are still demanding that those responsible be brought to justice.
Four police officers were arrested for allegedly tampering with evidence in the case but were released on bail for lack of evidence.
The CBI had exhumed the bodies of the victims on Sep 17. Doctors had then concluded that Aasiya was not raped.
