Daphne Caruana Galizia's alleged murderers were back in court on Monday morning as the compilation of evidence against them continued.

Here's a summary of the hearing's key testimonies:

• Laptop taken by investigators from Ms Caruana Galizia's residence shows the last data dated back to December 2015. She appeared to have been using another laptop when she was killed.
• Lawyers for accused request bail. 
• An on-site inquiry to be held in Bidnija on April 20. 
• Defence lawyers engaged with witnesses whether they actually saw the arrest warrant.

A minute-by-minute commentary of Thursday's proceedings:

12.18pm: The case is put off to Tuesday for submissions on bail. 

Defence lawyer William Cuschieri suggested that bail submissions could be made on Friday during the on-site inquiry, prompting a vociferous reaction by prosecution and parte civile lawyers.

“How could they be so insensitive? How could they think of discussing bail right on the spot where Daphne Carauana Galizia was murdered," lawyer and Nationalist MP Jason Azzopardi told Times of Malta.  

12.05pm: Court experts were meant to testify today but inspector Arnaud informs the court that they had not yet completed their reports.

11.50am: The vice squad officer says he saw copies of the warrant in hands of the inspector. Suspect Vincent Muscat was present during the Msida search. 

11.43am: Alan Zahra from the vice squad says he was assigned to the team led by inspector Joseph Mercieca to search Siggiewi residence of Vincent Muscat. Waited for forensic team, joined by Europol expert. The suspect's wife opened the door. His daughter was also present. 

After 6pm, the investigators proceeded to another residence in Msida, where search was conducted in presence of another daughter of Mr Muscat.

11.39am: Kenneth Mifsud, one of investigators from the vice squad, was involved in the search at George Degiorgio's apartment. He also says he did not see the warrant and not know the name of the foreign expert accompanying them. 

11.35am: Witness is asked if Ms Caruana Galizia had received any recent emails on the laptop. He says the last communication was in December 2015. Expert says he had no access to any other laptop used more recently by the victim.

11.33am: Court expert Alfred Cardona says he was appointed to analyse laptop and memory cards from Daphne Caruana Galizia's house. But the content was old and she probably used another laptop. Her more recent work was not on the computer.

Parte civile lawyers and inspector are requesting court to ensure that journalists' sources safeguarded. Defence lawyers are insisting their clients have right to know what is contained in expert's report.

Inspector Arnaud and parte civile lawyers agree that in this case Ms Caruana Galizia's laptop was an old, long unused one.

11.21am: Defence lawyer William Cuschieri argues that no warrant was shown, and all equipment was removed from the scene, including the child's PlayStation console. 

11.15am: Defence lawyer Martin Fenech is arguing why the police present at the search did not know the name of foreign experts present at the scene. Inspector Arnaud replies saying he had personally assigned the experts and may testify about it.

"All these experts will be testifying in the proceedings," a lawyer from the AG's office butts in.

11.05am: Next witness up is Ray Sciberras from the police vice squad. Together with two other officers, forensics and a member of Europol, they were instructed to search the residence of suspect George Degiorgio. The door was opened by his partner who had a small child with her. Mr Degiorgio was not present. Lawyer asks whether a search warrant was shown - the officer says he does not remember.

10.50am: Defence lawyer Martin Fenech asks the diver: "What else was there on sea bed?" The witness responds: "all sorts of rubbish. It's like a dumping area."

10.40am: Another diver takes the witness stand to say he found four mobile phones in the sea on December 4. "I collected them, resurfaced and handed them over to forensics," he says. Some batteries, SIM card holders and Nokia covers were found too.

Some background: The phones in the water just outside the shed where Mr Degiorgio’s vessel was berthed were identical to those the investigators believe were used in the murder. Others were unrelated but belonging to the accused.

10.30am: A second dive on December 6 yielded another Nokia phone, the witness says. The divers spent all week inspecting the seabed but the visibility was not good. They had been told to look for mobiles and items related to explosives. One of the Nokia phones had no battery.

10.26am: An AFM officer who assisted in searches in Marsa, near the potato shed where the suspects were apprehended, says two mobile phones (a Nokia and a Samsung) were retrieved from the water on December 4.  The area covered spanned some 10 metres from the quay. 

10.08am: As the court case resumes, former Nationalist Party leader Simon Busuttil says on Twitter he has just put new flowers in memory of Ms Caruana Galizia amid jeers from people outside court. 

9.57am: First witness is Keith Cutajar, the expert who extracted footage from CCTV located in more than 60 locations.

9.53am: Inspector Keith Arnaud says that the evidence is nearing the end. The respective parties are planning an on-site inquiry in Bidnija - the site of the murder - next week. 

9.51am: The parties are discussing a cigarette butt retrieved from the crime scene currently held by forensic experts.

9.42am: The three accused men - brothers Alfred and George Degiorgio and Vincent Muscat - have just entered the courtroom. Six officers wearing bullet proof vests watch over courtroom.

9.25am: The court sitting takes places hours after the memorial for the slain journalist - located right in front of the law courts - was once again cleared during the night. Pictures, messages and flowers in memory of Ms Caruana Galizia were removed by unknown individuals. The potted plants were spared.

9.20am: People are gathering inside the courtroom, with the hearing due to begin shortly.

Event timeline

Ms Caruana Galizia was killed in a car bomb blast on October 16 close to her home in Bidnija.

In December, police arrested 10 men in connection with her murder.

Three of those - brothers Alfred and George Degiorgio and Vincent Muscat - were charged with her murder. The others were released without charge.

Magistrate Claire Stafrace Zammit is presiding over the compilation of evidence. So far, she has heard how police:

1. Used the FBI's help to home in on suspicious phone numbers. One was linked to a remote-controlled device and went active at 2am in Bidnija on the day of Ms Caruana Galzia's murder. It received an SMS at the time the bomb went off and immediately went off-radar.

2. Believe that the phone which sent the bomb detonation SMS was an old Nokia 105. Police found several Nokia 105 phones at the Marsa shed where they arrested the suspects.

3. Triangulated cell tower data to work out that the killer SMS was sent from out at sea. George Degiorgio was seen going fishing on that day, and shortly after the bomb went off texted his partner "buy me wine, my love."

4. Received reports of a suspicious car regularly parked by tat-Tarġa Battery - an ideal vantage point for the killers - in the weeks leading to the murder. The car was subsequently never seen there again.

5. Found a "fresh-looking" cigarette butt with Alfred Degiorgio's DNA on it under a tree at the tat-Tarġa vantage point.

6. Europol experts accompanied local police on all key searches of the homes of the three accused homes as well as sites of interest, such as the Marsa shed where they were arrested.
