A disabled homeless man who died after being stabbed 183 times in a Dublin park was "the light in any room", his heartbroken sister has said.
In a powerful statement to the Central Criminal Court, Katie Muldoon said that the man who murdered her brother Adam has shown no remorse for the "gruesome" killing.
In a second victim impact statement, Adam's father wrote that the family "can't understand how anyone could be so callous and brutal to inflict such a death on such a sweet and innocent person".
Philip Dunbar (20) was yesterday sentenced to life imprisonment for the murder of 23-year-old Adam 'Floater' Muldoon at Butler Park, Jobstown Park, Tallaght on June 22 or 23, 2018.
Dunbar stabbed Mr Muldoon 183 times in an unprovoked attack with a fold-up knife and then went to a friend's house where he boasted that he had "slaughtered Floater" and "put him out of his misery" as he "begged for his life".
He was found guilty of murder by a unanimous jury verdict at the Central Criminal Court earlier this week.
Mr Muldoon's younger sister Katie delivered an emotional statement to the Central Criminal Court during the sentence hearing yesterday, saying that Adam had struggled from birth having been diagnosed with cerebral palsy.
He struggled to fit in, his sister said, and despite facing obstacles throughout his life, particularly following his mother's death, he kept fighting.
"He was the light in any room," she said.
When Adam and Katie's mother died, the family became separated and Adam moved to Tallaght where other teenagers would take advantage of him.
But he "overcame every challenge independently", she said, and would "have a giggle with anybody. He really wouldn't hurt a fly".
She said the day he was murdered her life crashed. When she was supposed to be celebrating her 16th birthday, her family held a wake for her brother.
She felt powerless and "everything has been downhill from there".
"My heart aches," she said, when she thinks of Adam's final moments and the fear he must have felt.
"Hearing how he begged for his life haunts me," she said.
At times, she couldn't even say her brother's name as it would cause her to have a panic attack.
Her physical and mental health had also began to suffer.
"There was no good left in the world. Everything was just dark," she said.
She said her brother didn't deserve such a "gruesome" death and said the family had to endure a trial because Dunbar pleaded not guilty and then continued to lie.
"His lack of emotion shows he has no remorse for what he has done," she said.
She thanked the people of Tallaght who had given evidence that helped secure Dunbar's conviction.
A second statement was written by Adam's father, Michael Bolger, and read to the court by Det-Gda Nuala Burke.
Mr Bolger said the family was "devastated" by his death and "can't understand how anyone could be so callous and brutal to inflict such a death on such a sweet and innocent person".
He said that Dunbar had caused "unimaginable despair, grief and heartache".
Det-Gda Burke also told the court that Dunbar had convictions for theft, for possession of drugs and for road traffic violations.
Mr Justice Paul McDermott said the deceased's life and the challenges he faced had been brought to the forefront by the "eloquent" statements made by his family.
He sentenced Dunbar to life imprisonment, backdated to June 24, 2018 when he first went into custody.
Counsel for Dunbar, Giollaíosa Ó Lideadh SC, indicated that his client intends to appeal the murder verdict.
Speaking outside the court, Superintendent Ian Lackey said the family of Adam Muldoon had been suffering since Adam's "senseless murder".
He said he hopes the verdict and sentence handed down will offer them some comfort.
