The Central Criminal Court has heard a broken blood-stained shovel handle was found in a house in Castlebar where the elderly Blaine brothers were beaten to death.
It was shown to the jury in the trial of Alan Cawley from Four Winds, Corrimbla, Ballina who denies murdering the two bachelors.
A number of items were taken from Jack and Tom Blaine's home in Castlebar after their home-help found their bodies on the morning of July 10 2013.
Among them a wooden shovel handle, which was shown to the jurors this afternoon.
They were told the broken end of it was heavily blood-stained.
The jurors were also shown a shovel head with a hole in it as well as a walking stick and a number of mop and brush handles found beside the body of Jack Blaine who was lying at the back door of their home.
His brother Tom was found in a pool of blood on the floor of his bedroom.
The State Pathologist Dr. Marie Cassidy said the evidence suggests he was struck in the head while lying on his bed.
Following his arrest, the court heard Alan Cawley told Gardaí he killed the two men because he thought they might be child molesters.
He admits killing them but has pleaded NOT guilty to both murder charges.
