The car of a man accused of murdering two British soldiers at Masserene was captured on CCTV hours earlier, driving just ahead of the gunmen's car, the trial will hear this week.
The prosecution will play footage in Antrim Crown Court showing Brian Shivers Mercedes in traffic in Magherafelt, Co Derry, allegedly followed three cars behind by the republican killers' green Vauxhall.
But the Sunday World understands the green Vauxhall's registration number can't be seen in the images.
The defence will argue it's a different Vauxhall to the one used at Massereene.
An expert witness will be called to point out differences between the car in the CCTV footage and the murder team's vehicle.
Last week, in a dramatic development, a DNA expert flown in from Australia by the prosecution wasn't called to give evidence. No reason was given by the crown for not using their own witness.
Leading Lurgan republican, Colin Duffy (43), and Brian Shivers (46) are accused of murdering two British soldiers and wounding two other Sappers and two pizza delivery men in the ruthless attack.
Mark Quinsey (23) and Patrick Azimkar (21) were gunned down as they collected takeaway food outside the Co Antrim barracks two years ago. Shivers and Duffy are pleading not guilty.
The court heard how DNA linking them to the double murder was found in very small amounts in the getaway car. DNA from seven others – six men and a woman – was also discovered in the vehicle.
Forensic scientist, Dr Emma Watson, said Duffy's full DNA profile was on the tip of a latex glove found in the getaway car. The chance of it coming from anyone but him was one in a billion, she added.
Duffy's partial DNA profile was also found on a seat belt buckle in the car, she told the court.
Challenging her evidence, the defence argued the forensic evidence was miniscule. The DNA on the glove tip alleged to be Duffy's weighed only five billionth of a gram. The DNA on the seat belt buckle was 100 billionth of a gram.
Shivers' alleged DNA found on matchsticks and a mobile phone in the car was also 100 billionth of a gram. Watson agreed the amount of DNA from the seat belt buckle, phone and matchsticks was low enough to be officially quantified as "zero".
Prosecution barrister, Terence Mooney, acknowledged the data was small but asked Watson: "Can reliable results come from those quantities of DNA?" She replied: "Yes they can."
