An associate of Yorgen Fenech "knew everything from A to Z" about Daphne Caruana Galizia's assassination, the murder middleman testified on Thursday.
Johann Cremona, who has not been charged in connection with the crime, was described as "Yorgen's postman" by Melvin Theuma.
Melvin Theuma was testifying in the compilation of evidence against Robert Agius, Adrian Agius, Jamie Vella and George Degiorgio who are accused of supplying the device that was detonated by remote control on October 16, 2017 to kill Caruana Galizia.
The group also face charges of killing lawyer Carmel Chircop in 2015.
"He knew everything, from A to Z. He knew that Yorgen was the mastermind, that the bomb was planted by three hitmen and that I was the messenger. He knew it all," Theuma told the court during an animated and often angry testimony.
