AMY Fitzpatrick's stepfather has admitted to gardai that he stabbed her brother Dean.
The Herald has learned that Dave Mahon told gardai he had a bust-up with his stepson and claimed he stabbed Dean (left) as he himself feared for his life.
The 42-year-old was released without charge yesterday afternoon and a file has been sent to the Director of Public Prosecutions.
It has also emerged that grieving mother Audrey did not find out her son Dean (23) had died until 12 hours after the stabbing.
A 12-inch carving knife was produced during the row and Mahon is believed to have told officers he stabbed Dean as he feared for his life.
A blade was later found close to the crime scene at the Burnell Square Apartments just off the Malahide Road, close to Clarehall.
Speaking from his father’s home in Santry after being released from garda custody yesterday, Mahon said: “It was a complete accident.”
Mahon said he did not know that Dean had died at the time of the stabbing.
He said he had gone to his father’s house following the incident and had gone straight to bed.
“I only found out the next morning when my dad told me when I woke up,” said Mahon, adding that he then called a friend and presented himself to gardai at Coolock.
He explained that Dean’s mother is now his main concern.
“I love Audrey so much and need to tell her how sorry I am. I will have to live with this for ever,” he said.
One source close to the investigation has said: “The suspect is adamant that he acted completely out of self-defence. He didn't even take a break during over 21 hours of questioning”, the source added. Seperately, sources said last night that gardai are still working on the theory that Dean had been the victim of an assault earlier in the week.
He had also recently received threats that he and a close friend would be slashed.
At the scene of the killing, Audrey yesterday wept openly and laid flowers of tribute to Dean with the words ‘My chicken’ on the card.
