She told, how after carrying out the horrific attack on the vulnerable 65-year-old in his Balbriggan home, the killer locked his front door from the outside – sealing off any chance the father-of-three had of calling for help.
Christy’s phone was also missing from the scene but it’s understood this may have been lost by or stolen from Christy in the days prior to his killing.
The relative, who asked not to be named, said also she believes Christy must have known his killer as he wouldn’t have opened the door to someone he didn’t know.
“Christy was one of those people who locked up early,” she said. “So, he would have had to unlock that door from the inside to let that person in and he wouldn’t have done that unless he knew who he was opening the door to.
“And that’s the horrible part of it.
“Because he would have opened the door delighted to see this person.
“But that animal came for a different reason. Whoever the animal is, if Christy even had one breath left in him, he didn’t give him a chance.
“He took the keys of the house and he locked the door from the outside.
“So, if Christy had a breath left in, he couldn’t have called for help.”
Separately, sources have confirmed to the Sunday World that there was no evidence found of a forced entry at the property.
Christy had a medical condition as a result of an accident 20 years ago in which he sustained severe head injuries. He recovered after a period on life support, but his injuries resulted in a life-long medical condition.
The popular pensioner was found by one of his daughters lying dead in his home in Dun Saithne Green, Balbriggan, on Wednesday afternoon.
He had sustained severe injuries to his head and upper body.
Gardaí believe at least some of the injuries were inflicted with a weapon which was not located at the scene.
Speaking with the Sunday World, Christy’s relative paid tribute to him as a generous soul who would do anything for anyone, including giving you the last euro in his pocket.
“Christy wouldn’t have much money as he lived off his disability payment, but he’d happily give you the last euro out of his pocket,” she said.
Originally from Garristown in Co. Dublin, Christy, a former employee of Dublin County Council, lived in Whitechapel in Clonsilla for a period before moving to Balbriggan after a horrific accident 20 years ago.
“He wasn’t expected to pull through after the accident. But he did pull through after a long period on life support. After that, he wasn’t able to work anymore,” the relative said.
“He wasn’t able to manage stairs because the head injury affected his balance and that was why he was given the house he was in.
“He had two daughters and a son and Christy adored them. He was really gentle and easy-going.
“He just couldn’t see any fault in anyone. “If anyone was short he’d say go on there and take that. He’d give money to anyone if they needed it.
“He was down at his mother’s one day when he got a phone-call from an elderly man giving out that he had been meant to bring him up bread and milk.
“‘Oh, Jesus,’ says Christy, ‘I forgot but I’ll get it for you on the way back. I’m down at my mother’s.’
“And that was just the way he was … he’d do anything for anyone.
“No-one could ever say a bad word about him. He adored his kids. As long as they were happy, he was happy.”
“I don’t know what we are going to do without him. It’s going to be a long process getting through this.”
A senior source who spoke with the Sunday World said the brutal nature of gentle Christy’s death had affected even the most experienced of gardaí.
“This was a vulnerable man who was living a simple life within that community,” the source said. “Despite his medical condition, he made the best of things, he had friends, he enjoyed going for a pint and an occasional flutter on the horses.
“There is no reason for him to have been targeted like this.
“And Gardaí are determined to apprehend the person responsible.”
The Sunday World understands that Gardaí have harvested CCTV from a number of cameras in the Dun Saithne estate in the hopes Christy’s killer may have been caught on camera.
They are also appealing to his network of friends and neighbours to come forward with any information they may have on the killing.
The investigation into Christy’s killing is being led by Superintendent Paul Franey and the team at Balbriggan Garda station.
He said: “Christopher was a quiet man who lived alone and was vulnerable because of a medical condition.
“I am appealing to any person who was in the Dun Saithne Green, Dun Saithne Crescent or wider Dun Saithne area between 8pm Tuesday, November 23 and 2pm, Wednesday November 24, whether you believe you saw anything of interest or not to contact Balbriggan Garda Station.
“I want to appeal to residents or persons with cars parked in the Dun Saithne area who may have CCTV or dashcam footage, if Gardaí have not been in contact with you to please come forward with that footage.
“I am appealing to anyone with any information on the murder of Christopher Hall to contact gardaí at Balbriggan Garda Station 01-6664500, the Garda Confidential Line 1800 666 111 or any Garda Station.”
