This is the exact spot in the Maltese countryside where political journalist Daphne Caruana Galizia was assassinated on the 16 October last year. That afternoon, Daphne left her home in the village of Bidnija just before 3pm. As she drove down this hill, a remote-controlled bomb detonated under the driver’s seat – hurling the vehicle off the road in a deadly explosion. I heard her screaming. But as soon as she screamed she became a ball of fire. Six months on, police investigators have been painstakingly piecing together a detailed picture of how they believe Daphne’s killers carried out their gruesome task. The first arrests in the case occurred roughly 7 miles from where Daphne was killed, here, in the Maltese capital of Valletta. In the early morning of the 4 December 2017, police and army units raided these warehouses in the port area of Marsa. They arrested three men widely reported to be known to police: brothers George and Alfred Degiorgio, and their associate Vincent Muscat. It was here that police suspect Daphne’s murder was planned. Investigators assumed the bomb had been triggered remotely by a mobile phone; so the question was: who was making calls that day, and from where? Thousands of calls had to be sifted before investigators found what they were looking for: the phone numbers of two devices that appear to have been used to detonate the bomb. The first device was a basic Nokia handset – this sent the bomb’s activation code by text. A second device had a sim card installed, which received the code and then detonated the bomb. Police called this “the God device”. On the day of Daphne’s murder, this is how investigators believe events unfolded. At 01.41am the ‘God device’ was switched on – sending a signal from Bidnija, where Daphne’s car was parked outside her home. According to police, Alfred Degiogio spent the night in Bidnija. Police believe he was the ‘lookout’ and in the days before had been obeserving her movements from the ridge line that overlooks the house. Meanwhile, according to the police, phones suspected to belong to George were signalling from Valletta’s Grand Harbour. Investigators matched the locations with CCTV footage and identified a distinctive small boat called the Maia. At 2:55pm, the Maia came to a stop and idled along a sheltered stretch of water beneath a war memorial known as the Siege Bell. Around the same time, Daphne was getting in her car to go to the bank. Minutes later, there were two phone calls to the boat – both from Bidnija. A text message is sent from the boat to the ‘God device’, detonating a bomb placed under the driver’s seat of Daphne’s car. At 3:20pm phone data shows the Maia, heading back towards the Grand Harbour. Ten minutes later, George sends a message from his personal phone to his partner. “Buy me wine, my love”. She replied: “OK”. This version of events is based on information given to an examining magistrate, who has yet to decide whether or not the three men should stand trial. The accused men have all pleaded not guilty.
