Arrest expected in cold-case probe into 1984 murder of mother of two
An arrest in the investigation of the 1980s murder of Marie Tierney is expected over the coming days after a significant witness came forward.
It is understood that the Garda investigation team have acquired crucial new evidence linking a suspect to the murder of the mother of two.
Gardaí have conducted an exhaustive investigation since 2017, including examining 500 lines of enquiry.
It is believed that the suspect was known to Ms Tierney and is living in the Kilkenny area.
New technology has also been pivotal in progressing the investigation.
Ms Tierney's remains were exhumed and a post-mortem examination took place last October. A source described the development as highly significant to the investigation.
Ms Tierney was reported missing by her husband Jim Tierney on October 22, 1984.
He told gardaí that she had left her home at Clinstown, Jenkinstown, at about 10.30pm the previous night in the family car.
The vehicle, a Renault 18, was located at Newpark Fen the following day.
On December 21, 1984, her body was located in a ditch. She had been strangled.
