US police believe an Irishwoman killed three members of her own family before taking her own life.
She has been identified as the suspect in an apparent murder-suicide in Nevada.
On Wednesday, Joan Huber from Kerry was found dead along with her husband and their two teenage sons in a house in Reno, Nevada.
She is from the Killarney area but had lived in the US for many years.
Reno police have now identified the 53-year-old as the suspect in this week's incident.
They believe that, in the days before their bodies were found, she shot her husband, Adam, and their two children - 17-year-old Adam and 16-year-old Michael - before taking her own life.
The weapon used has been identified as a firearm.
Reno police say they are still actively investigating the case and there is no known motive at this time.
