Gardaí investigating the murder of Ballymum mother-of-two Lisa Thompson have issued an appeal for a man who handed a document into a garda station two days after the killing to come forward.
Ms Thompson was found stabbed to death at her home in Sandyhill Gardens, Ballymun, north Dublin, last Tuesday afternoon, May 10.
Her body had lain undiscovered in the terraced property for several days.
In a statement this morning, the force said: “On the morning of Thursday, 12th May 2022 at approximately 7.10am, a male handed a document in the name of the deceased Lisa Thompson to a Garda staff member at the front door of Finglas Garda Station and left on foot.”
“An Garda Síochána 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.”
Gardaí did not provide any further information about the document.
Her phone is being examined, and detectives hope it will offer a clear indication of who she was in contact with and met in the final days of her life.
That information, combined with forensic evidence gathered from the scene, is expected to help gardaí narrow down a list of suspects for her murder.
Detectives have been focusing on establishing Ms Thompson’s movements the weekend before her death and who she had been with during that time.
There were local reports of two men seen fleeing from her home Sunday morning May 8, two days before her body was found.
Gardaí have interviewed neighbours who may have noticed comings and goings at the property.
However, it is not known precisely when she died.
There was no sign of a break-in or a struggle or fight, a source confirmed. This supports a theory that Ms Thompson probably knew her killer.
Detectives are keeping a “completely open mind” in relation to her killing, but conceded she had become “vulnerable” and “inadvertently associated” with local criminal elements.
A source said: “She had personal problems for around 12 months. It is a very tragic case, she was very well respected locally, but it seems her life was beginning to unravel.”
While the murder weapon is understood to have been recovered, gardaí have not disclosed what it is.
Garda Superintendent Darren McCarthy, of Ballymun garda station, said investigating officers had no clear suspect for the murder of the former youth worker.
A concerned neighbour raised the alarm by calling 999 and asking for an ambulance just after 3pm last Tuesday. When paramedics arrived at the house they called gardaí.
“Lisa was a 52-year-old woman and well-known in her local community, which is shocked over this violent and traumatic death,” Supt McCarthy said.
“She had been the subject of a serious assault and suffered significant injuries.”
The senior officer said gardaí were unaware of any threats made against Ms Thompson or any reason why she would fear for her safety.
He said officers also wanted to examine any video footage recorded by motorists and others around the Sandyhill area of Ballymun since Saturday May 7.
Any footage recorded in nearby streets, including Marewood Crescent and Balbutcher Lane, was also being sought.
Gardaí in Ballymun are appealing to anyone with information to come forward and help with their enquiries.
