The jury in the trial of the man accused of murdering Detective Garda Adrian Donohoe has been watching CCTV from the area where a Volkswagen Passat was stolen days before the fatal shooting.
The Central Criminal Court heard the burglary happened three days before the alleged robbery and murder at Lordship Credit Union.
A Passat was used in the robbery and later found burnt out in the North.
Aaron Brady (29) denies murdering Det Gda Donohoe, who was then a member of An Garda Siochana acting in the course of his duty, at the credit union in Bellurgan, Co Louth, on January 25, 2013.
The accused, of Crossmaglen, Co Armagh, has also pleaded not guilty to the robbery of around €7,000 in cash and cheques from Pat Bellew.
Civilian intelligence analyst Edward McGoey gave evidence yesterday of six contacts in the early hours of January 23 between phone numbers of interest to the investigation team.
They included a failed call Mr Brady made to one man at 1.44am and a call made by another suspect, who cannot be named, a minute later.
These were the last phone contacts from the Brades 2 phone attributed to the accused and a phone used by the other suspect until the following afternoon, the court heard.
Footage was then played of a BMW 5 Series arriving at Ballymacscanlon service station shortly before 2am that day.
Det Gda Gareth Kenna said the suspect and his brother are seen exiting the vehicle, while a third person can be observed in the rear.
Footage from various places in Co Louth from the morning of January 23 was then shown to the court.
Det Gda Kenna said footage from Sharkey's Bar, Clogherhead, showed a car consistent with a BMW 5 Series going in the direction of the nearby Hillcrest estate at around 3am.
He agreed with prosecuting counsel Lorcan Staines that a Passat had been stolen from the estate early on January 23.
The jury will continue hearing evidence today.
