DNA on screwdriver matched deceased and murder accused, court hears
DNA on a screwdriver found at the scene of a fatal stabbing matched the deceased and one of the two men accused of his murder, a trial at the Central Criminal Court has heard.
Sandra McGrath of Forensic Science Ireland said that she matched the blood to Ger Hogan (34) of Raheen Square, Ballinacurra Weston.
Mr Hogan and his co-accused Dylan Hayes (22) of The Crescent, Kilteragh, Dooradoyle, Co Limerick have pleaded not guilty to the murder of Shane Murphy at The Grove, Pallasgreen, Co Limerick on April 30, 2015.
Ms McGrath told prosecuting counsel Paul Burns SC that she examined a number of items taken from the house in Pallasgreen.
The screwdriver was a standard Phillips head with a black-and-yellow handle. It had blood staining on the tip, along its length and on the handle. When she generated DNA profiles from the stains, she found they matched Mr Hogan and the deceased Shane Murphy.
Ms McGrath estimated the chances of those samples having originated from an unknown person at one in a billion.
She also took four blood samples from a serrated steak knife with an 11cm-long blade that was found at the scene. All of those stains matched the profile of Shane Murphy.
Four blood stains on Dylan Hayes's coat and trousers matched the DNA profile of Shane Murphy.
The jury also saw CCTV footage showing Ger Hogan visiting a Centra in Pallasgreen. Sergeant Michael Reidy said that the footage showed Mr Hogan twice entering the shop to buy alcohol on Wednesday April 29, one day before Mr Murphy lost his life.
Sgt Reidy said Mr Hogan bought a total of eight cans of Karpackie beer and 12 cans of Druid's Cider on the Wednesday. The following morning he returned and bought four cans of beer and a breakfast roll.
Sgt Reidy also identified Jodie Byrnes and Ailish Flood, who the court has already heard were staying at the house in Pallasgreen at the time. Sgt Reidy said Ms Byrnes and Ms Flood twice entered the Centra on the Thursday evening to buy alcohol.
The trial continues tomorrow in front of Justice Patrick McCarthy and a jury of five women and seven men.
