Anne O’Sullivan (née Cronin), the wife and mother of a tragic murder-suicide incident near Kanturk, Co Cork late last year, has passed away at the age of 60 following an illness.

A brief message on says that O’Sullivan “passed away peacefully on 7th April 2021” and that she is “lovingly remembered by her family, relatives, and friends.”

Due to current guidelines, O’Sullivan’s funeral will be private but will be live-streamed online on Friday, April 9.

The family, who has thanked people “for your understanding and cooperation at this difficult time,” has requested no flowers and instead directs donations to be made to Cliona’s Foundation, which provides financial assistance directly to parents of children with life-limiting or chronic complex care needs across Ireland.

On October 26, 2020, Anne's husband Tadg, 59, and the couple’s two sons Mark, 26, and Diarmuid, 23, were discovered dead on the family’s farm outside of Kanturk, Co Cork. Anne, who had been discharged from hospital just two weeks earlier after surgery for a terminal medical condition, fled the scene raised the alarm to neighbors about the incident.

The deaths of three men are alleged to be a double murder-suicide.
