A colleague of James Ireland and Karl Demetrius has given evidence in court.
Nathan Bignell - a trainee parts inspector working for a company contracted to Airbus UK, in Filton. He told the court we was aware the two of them were close friends.
He told the court he thought Ireland drove a light blue Fiesta, and had seen the car outside their place of work.
The witness told how the police took a statement from him on 6 March this year.
He recounted how in February he heard Karl Demetrius take a phone call at work which lasted 5 or 10 minutes. James Ireland was sat nearby and the court heard that Karl Demetrius spoke to him. Mr Bignell said he could hear parts of the conversation.
"He was talking about a job he'd just got...collecting or delivering something and they would get paid quite well for doing it" - the court heard. When asked, the witness said he was not positive who was on the phone, but he heard Karl Demetrius' brother's name mentioned.
"Jamie was very interested" - Bignell told the court. He also said he'd joked with the pair about what goods they would be taking, asking if it was "weed". He said the pair ignored him.
The court also heard that the witnessed advised them "If you're doing something dodgy, I wouldn't use the work van" as it was not worth getting in trouble over. The witness said that the pair then moved away from him, and he did not hear anymore. He said he saw that Ireland's car had left.
Bignell told the court that he saw the pair again a few hours later, and they seemed "very happy" and in good spirits. They both made comments that they could go on a nice holiday with the money earned from this job.
On the Monday, the witness said the pair seemed "secretive" and were quiet - this was unusual as they were normally very outgoing.
The next day, the court heard that police officers arrived at their place of work.
The defence asked the witness about the duties of Ireland's job, pointing out that he would often use one of three work vehicles that were available. These were only supposed to be used for work purposes, the court heard, and should be signed out. The lawyer suggested that a lack of supervisors might have led Ireland to "take liberties" at work, looking at his phone, computer and watching television while at work.
The lawyer asked if the witness was aware that Ireland was "regularly using the work van for his own use", going to the shops and taking someone to an appointment.
The witness said that on occasion Ireland had asked him for some help - making it clear that he had difficulty with reading and writing and needed help using the internet. He also told the court he had some difficulty with his speech. The defence asked if he knew that these difficulties were in part caused by his suffering from ADHD or autism.
