Detectives continued to question a woman last night in connection with the fatal stabbing of a man at his home in south Dublin on Thursday evening.
Tyrone McKenna, 42, was discovered by his father, Tom, slumped at the bottom of the stairs at their home in Marley Court estate in Rathfarnham.
The father rang 999 and when the ambulance crew arrived, Mr McKenna was already dead.
Tom McKenna yesterday said there was another person, known to both him and his son, in the house at the time, but didn’t appear to know what had happened.
Gardaí were alerted and sealed off the area, pending a forensic examination of the scene and the arrival of Dr Michael Curtis, the deputy State pathologist.
The preliminary postmortem indicated that the injuries were not consistent with a fall and that he appeared to have suffered a knife wound to his back.
The body remained at the house overnight, before being removed for a full examination yesterday.
Detectives moved on a suspect yesterday morning and detained her under Section 4 of the Criminal Justice Act in connection with the murder.
The woman, aged in her 40s, was known to the victim. She was arrested at a different location to Mr McKenna’s home.
She was questioned at Blackrock Garda Station for an initial period of six hours, before her detention period was extended.
She can be held for a total of 24 hours, excluding sleep breaks.
The father and son had been living at the home, but it is thought that another person also spent some time there.
A detailed technical examination continued at the house yesterday, which is in a quiet leafy residential area. Forensic experts were conducting tests and taking samples at different locations in the house, including upstairs and along the stairs.
Tom McKenna yesterday told the media that he had discovered the body after he returned home at around 5pm.
“He was there at the foot of the stairs. I touched him and I knew straight away, I rang 999,” he said.
He said his son’s body was lying slumped at the bottom steps.
“It was if he had slid down, there was blood on the wall, there was blood on the landing.”
Tom explained that Tyrone’s mother was living in England. He said his son had been married, but that the relationship broke down some years ago.
Neighbours described the victim as a lovely man, but who generally kept to himself. They described Tom as a great neighbour and expressed their deep sorrow at the tragedy.
