This could be interesting. A story from Malta I picked up way back last year.

Investigators have identified a group of at least three Maltese nationals who they believe masterminded the killing of anti-corruption journalist Daphne Caruana Galizia 13 months ago, The Sunday Times of Malta reported on Sunday.

It did not reveal their names, but quoted high-ranking officers leading the murder probe as saying that their investigation was at a “very advanced stage”.

…

The newspaper sources would not give any indication of whether the masterminds came from the criminal, business or political sectors.

…

As I said then, car bombs make a statement. Hopefully, prosecutors will make one as well.
