Case closed? Not quite There can be no justice for Caruana Galizia if the alleged involvement of the PM’s former chief of staff Keith Schembri, through his assistance to one or other players in this plot, is not thoroughly investigated 28 February 2021, 3:23pm The arrest this week of three more men suspected of involvement in the Caruana Galizia assassination, as well as the 2015 Carmel Chircop murder, was undeniably a major breakthrough for police. It also stemmed from the decision of one of the original suspects – Vincent Muscat – to accept a plea bargain. This has, in fact, been the pattern of the investigation: Muscat had already pointed out Melvin Theuma, the assassination middleman, to investigators; and Theuma in turn accepted a Presidential pardon to tell police all he knew about the assassination.
