A man has been sentenced to life in prison for the murder of his mother in 2019.

Tomasz Krzysztof Piotrowski, 35, was sentenced today by Mr Justice Michael White.

The decapitated body of Elzbieta Piotrowska was discovered at her home at Clonmore in Ardee, Co Louth, on 8 January 2019. 

The 57-year-old, who came to Ireland with her husband from Poland, had also sustained serious stab wounds.

An axe and stanley knives were found close to her body.

Her son was arrested within two-and-a-half hours of the murder and was subsequently deemed unfit to be tried, having been assessed by psychiatrists at the Central Mental Hospital (CMH) in Dundrum, Dublin.

However, it emerged during a subsequent consultation that he accepted that he had lied to psychiatrists in order to get a diagnosis of schizophrenia and a lesser sentence. 

Two consultant psychiatrists disagreed on whether Piotrowski was fit to stand trial, but Mr Justice Michael White ruled last week that he could find his way around navigating a plea, follow the evidence and make a proper defence.

Today, he was arraigned in the Central Criminal Court and pleaded guilty to the murder of his mother.

The court heard Piotrowski had repeated delusional beliefs that Elzbieta was not his birth mother and that she was performing black magic on him.

When gardaí checked his phone they found a false DNA test, which showed Elzbieta was not his mother and Piotrowski had sent this to other family members.

However, this was discounted by Forensic Science Ireland, whose tests showed that his parents were his birth parents.

Piotrowski had developed psychiatric issues because of drug abuse two years earlier and owed €7,000 to drug dealers, which his parents had paid off from their "limited life savings".

Gardaí also recovered photographs of Piotrowski kissing his girlfriend while, unbeknownst to her, he was holding an axe behind her head and a photo of a stairs and hallway with an effigy of a bloodstained body.

Mr Justice White described it as the most tragic of cases and sentenced Piotrowski to the mandatory term of life in prison.
