Gardai are urgently trying to trace an unidentified man who handed in a driving licence belonging to murder victim Lisa Thompson.
Investigators believe the mystery person could be holding key information over the mum-of-two’s brutal killing.
Ms Thompson, 52, was stabbed up to 12 times at her home at Sandyhill Gardens in the Ballymun area of North Dublin.

Gardai believe she may have been dead for up to three days before her body was discovered on Tuesday, May 10, at around 3.30pm.
Two days later, at around 7.10am last Thursday morning, a man walked into Finglas Garda station with a driving licence belonging to the dead woman.
He handed it to a civilian staff member and said he did not want to speak to gardai.
The man then walked away without leaving his name or contact details.
Although he was captured on CCTV, investigators have been unable to identify him.
Gardai are anxious to talk to the man to establish how he came into possession of the personal document and if he has any information regarding the murder.
A Garda spokesman said: “An Garda Siochana in Ballymun are appealing to this male to make urgent contact with the investigation team at Ballymun Garda station at 01 666 4400 or the Garda Confidential Line on 1800 666 111.”
The Garda said detectives continue to keep an open mind on the murder and have yet to identify a suspect.
They are continuing to follow a number of lines of inquiry, including information which neighbours passed on regarding two men seen near her home on Sunday morning.
Investigators believe Ms Thompson knew her killer as there were no signs of forced entry into her home.
She was mother to a 12-year-old girl and a boy of 14.
The victim’s phone continues to be examined as does other evidence taken from the scene in a bid to trace any DNA.
