An inquest is due to open on Wednesday into the murder-suicide deaths of three brothers in North Cork.
Johnny Hennessy killed his brothers Paddy and Willie at the family farmhouse in Curraghgorm near Mitchelstown last February.
Shortly before midnight on February 25th the body of Paddy age 60 was discovered in a farmyard and Willie, 66 in a nearby shed at their family farm.
They both suffered horrific head injuries.
Johnny Hennessy is understood to have then driven to a farmhouse at Killacluig, Mitchelstown, where he parked and walked over several fields to the River Funshion where he took his own life.
It's thought there may have ben a row amongest the brothers known locally as ther Saints over the sale of cattle and the distribution of wood on the family farm.
The men were discovered by Paddy's daughter Elaine.
The Garda ombudsman GSOC launched an investigation into contact Gardaí had with Johnny Hennessy on the Thursday evening before the alarm was raised.
Gardaí from Mitchelstown are understood to have telephoned him but he told them all was okay.
