The trial heard that Eoin O’Connor was a drug dealer in Dublin who had drugs stolen from him six days before his murder.
He had sold drugs to Lawrence’s South African boyfriend Neville van der Westhuizen, who owed him €70,000.
Lawrence and her boyfriend lived in St Patrick’s cottage at Lough Sheelin, near the shoreline which was approximately 100 metres from Inchicup Island.
The prosecution said Lawrence shot Eoin O’Connor in the stomach, but it was not fatal.
They said he was then shot in the head by Mr van der Westhuizen.
Prosecuting counsel Michael O’Higgins said that Ruth Lawrence intended to kill him and that Mr O’Connor may have “grappled” with Mr van der Westhuizen before he “finished him off”.
Anthony Keegan, who arrived with Mr O’Connor, was shot in the neck and head.
The prosecution said the two men were shot in a field near Patrick’s Cottage and the bodies had been moved to the island.
