An alleged tiger kidnapper was seen buying a litre of milk at a petrol station in the early hours of the morning of the alleged offence, a jury has been told.
Jonathan Gill (35) is accused of kidnapping a Drogheda postal worker, his partner and their 10-week-old daughter before stealing more than €600,000 from the man's workplace.
It is alleged that Mr Gill was one of a group of five who were involved in holding the family hostage in their own home before moving them to a shed about 90 minutes' drive away.
Mr Gill, of Malahide Road, Swords, Dublin, has pleaded not guilty at Dublin Circuit Criminal Court to falsely imprisoning Warren Nawn, Jean Marie Nawn and their baby in Drogheda between August 1 and August 2, 2011.
The trial has previously heard that the baby started crying as they were being taken to the shed in Swords, where they were held overnight.
Ms Nawn said the child was hungry and the raiders stopped to buy him a litre of milk.
It is alleged that gardai later recovered the empty container from a partially burnt-out vehicle after the kidnapping ended.
Yesterday, a detective gave evidence that, in the aftermath of the kidnapping, he canvassed 24-hour shops in search of one that sold a litre of milk in the early hours of August 1, 2011.
Staff at the Topaz Garage in Balgriffin said they had sold a litre of milk during that time.
The detective told Vincent Heneghan, prosecuting, that he then pulled up the CCTV footage from the garage.
He said he saw a male on the footage buying milk at 5.14am, who he identified as the accused.
The trial continues before Judge Elma Sheahan and a jury.
