Matthew Caruana Galizia faced the men accused of supplying the bomb that killed his mother when testifying in court on Tuesday.

He recounted once again how he saw body parts from his mother’s butchered body as he approached the burning car on that fateful day.

Daphne Caruana Galizia was murdered in a powerful car bomb explosion on 16 October 2017.

Matthew was testifying in the compilation of evidence of brothers Adrian and Robert Agius, and their associates Jamie Vella and George Degiorgio.

Robert Agius and Jamie Vella are accused of supplying the bomb that killed Daphne Caruana Galizia. Degiorgio is facing separate proceedings on the same case.

Adrian Agius is accused of masterminding the murder of lawyer Carmel Chircop, while Vella and Degiorgio are charged with carrying out the murder.

In his testimony, Matthew Caruana Galizia said that in the period that his mother was murdered, she had been working on a leak from Electrogas.

“My mother was under a lot of pressure… there was a major investigation she was working on, she was constantly being harassed, and her general demeanour was one of stress. But she had made it a part of her life and she was used to dealing with it. It was just a regular morning working together. She was flustered because she was going to be late to the bank appointment,” Caruana Galizia told the court.

His mother had left the family home to attend a bank appointment since her accounts had been frozen by then minister Chris Cardona as part of a precautionary measure in libel proceedings.

Reliving the horrible experience, Matthew Caruana Galizia told the court that while running down the hill towards the burning car he came across a lower leg detached on the ground.

“I said, ok this is my mum's leg. It was severed below the knee. The car's horn was blaring. A woman with a crying child was standing close by and asked what to do. I told her to call the police,” he recounted.

The Agius brothers, known as Tal-Maksar, and Vella had long been suspected of having been the bomb suppliers in the Caruana Galizia murder case. They had been arrested in December 2017 but later released with no charge.

They were arrested in February this year, shortly after Vince Muscat pleaded guilty for his part in the Caruana Galizia murder and was sentenced to 15 years in prison after a plea bargain agreement. Muscat was granted a presidential pardon to tell all on the Chircop murder and helped police with key evidence on the Caruana Galizia murder that pinned one of the Agius brothers to the crime.

The case continues on 6 December.
