Man was found naked in a field after killing his Cork wife, court told

The jury will have to assess if James Kilroy was "simply guilty of murder" or if he was insane at the time of the killing or suffered from a mental disorder that diminished his responsibility

Evidence will be given, the court heard, that James Kilroy (pictured) was displaying "erratic behaviour" and was found naked in a field in the Westport area.

A 49-year-old man was found naked in a field after he killed his wife at their rural Co. Mayo home nearly four years ago, a jury has heard.

It was during the opening of the trial of James Kilroy at the Central Criminal Court on Wednesday that a prosecuting barrister said that a jury will have to assess if he was "simply guilty of murder" as the State contends or if he was insane at the time of the killing or suffered from a mental disorder that diminished his responsibility.
