Daphne Caruana Galizia's sister has told reporters working on the Daphne Project that the family cannot hand over the slain journalist's laptop because they don't trust the authorities.

Earlier today, one of the journalist's sons said he did not know where the laptop was.

A consortium of 18 news organisations are pursuing the stories that had been followed by slain journalist Daphne Caruana Galizia, and will be publishing the work The news organisations include the New York Times, The Guardian, and Süddeutsche Zeitung, the newspaper behind the Panama Papers revelations. The project was organised an investigative non-profit organisation Forbidden Stories.

Investigators were frustrated by the lack of trust the family had, reports from Daphne Project journalists read.

Daphne Caruana Galizia's sister, Corinne Vella, was contacted by the Daphne Project, who said that the slain journalist would never want her laptop given to the authorities, and said that the journalist always hid it before leaving home.

She said that Daphne Caruana Galizia knew that whatever information the police receive would go to the people she investigated in government.

Reports quote Corinne Vella as saying that it's as though they are being asked to hand over the laptop or they won't investigate. "We can't do that. We just don't trust them," Daphne Project journalists reported.

Earlier today, Matthew Caruana Galizia said "I would burn my mother's laptop in front of the police, if I knew where it was."
