A “major businessman” who the late Daphne Caruana Galizia had investigated has been suspected of masterminding her murder, according to a stunning report by Sunday Times of Malta.

The report states Caruana Galizia had investigated the businessman’s dealings but that the two were never involved in any legal battles or public spats.

Investigators are “quite certain by now that Daphne Caruana Galizia was murdered because of what she wrote or what she was about to reveal”, the newspaper said, quoting sources close to the investigation.

Moreover, the report claims police are zeroing in on two other suspects who could have been involved in the commissioning of the murder – one connected with the gambling scene and the other with the smuggling underworld.

Police have yet to interrogate the three suspects, with sources stating they are awaiting more rock solid evidence against them before prosecuting them.

Caruana Galizia was killed in a car bomb outside her Bidnija home around two years, on 16th October 2017, an assassination which rocked Malta. Two months later, three men – George Degiorgio, his brother Alfred and Vince Muscat – were arrested after police found evidence linking them to the planting of the bomb.
