The jury in a Dublin murder trial has been shown CCTV footage of a 33-year-old man being shot in a city pub four years ago.
Dubliner John Carroll died on the night of 18 February 2009, after being shot a number of times as he socialised in Grumpy Jacks pub in The Coombe.
Christopher Zambra, 38, of Galtymore Road, Drimnagh, has pleaded not guilty to murder.
The Central Criminal Court heard that it is not alleged that Mr Zambra shot Mr Carroll, but that he organised the killing.
CCTV footage from the pub was played to the jury showing the moment around 9.30pm when the gunman entered the pub.
The killer, who was wearing a motorbike helmet, was seen to open fire on a man as soon as he walked in the door.
Customers were seen dashing from the area while the gunman continued shooting.
The footage lasted only seconds.
The trial is expected to last between four and six weeks.
The jury also heard medical evidence that Mr Carroll sustained four gunshot wounds that night, including two to his back.
Patrick Gageby Senior Counsel, prosecuting, read a statement from Dr Una Geary, who was the consultant at St James's Hospital emergency department, where Mr Carroll was treated.
She said Mr Carroll was deeply unconscious when he was brought in that night.
She said his heart rate was abnormally high while his blood pressure was low, consistent with major haemorrhage.
She said that the patient went into cardiac arrest and that emergency surgery was carried out.
He was discovered to have lacerations to his diaphragm and liver, as well as massive abdominal bleeding.
She said that despite the surgery, and litres of fluid being drained from his chest and abdomen, Mr Carroll died from his wounds.
Mr Gageby also read a statement from Mr Carroll's father, Charlie Carroll, who said he last spoke to his son at 9pm that night.
He said his son had been watching a Manchester United match and had called to tell him that the team was winning 3-0.
A few hours later, Mr Carroll identified his son's body for gardaí in hospital.
The trial before Mr Justice Patrick McCarthy and a jury of eight women and four men continues.
