Robert O'Connor triple murder trial

Overview

Robert O'Connor is facing trial in the Central Criminal Court for the deaths of his parents, Mark and Louise, and his brother, Evan, in Drumgowna, Co Louth. The killings occurred between September 28 and 29, 2025. O'Connor has entered pleas of not guilty by reason of insanity or, alternatively, guilty of manslaughter based on diminished responsibility.

During the proceedings, it was revealed that the victims sustained a combined 139 stab wounds. While expert psychiatrists agree that O'Connor was experiencing a relapse of schizophrenia at the time of the incident, they disagree on his legal culpability. The defense argues he met the criteria for a special verdict of not guilty by reason of insanity, asserting he did not know his actions were wrong. Conversely, the prosecution’s expert testified that while responsibility may have been diminished, O'Connor knew his actions were wrong, citing cocaine use and a failure to take medication as contributing factors.
