THE post mortem examination of one of the three men killed in a shooting incident in Kanturk on Monday will get underway this morning.
Examinations have already been conducted on the two other bodies yesterday by the Assistant State Pathologist, Dr Margaret Bolster.
Gardaí believe the results of the post mortems will be key to determining the exact sequence of events that led to the fatal shootings of 59-year-old Tadgh O'Sullivan, his 25-year-old son Mark and 22-year-old son Diarmuid at two locations at the family farm at Assolas, between Kanturk and Castlemagner, on Monday afternoon.
The third post mortem will get underway this morning at 11am.
Gardaí did not reveal the results of the post mortems completed yesterday.
They said that the sole survivor of the family, Tadgh's wife Ann, has been helping investigators as they try to piece together the final hours at the house before the shootings.
House to house enquiries have been carried out in the area and gardaí are also planning to examine CCTV footage from the nearby village of Castlemagner.
They are hoping to establish a picture of the actions of the O'Sullivan family on Sunday, in the hours before the shooting.
Gardaí are investigating if the incident is connected to an inheritance dispute.
The O'Sullivans were well known in the area, and Mr O'Sullivan had worked in a local garage, and was not farming.
The 150-acre farm belonging to the family was rented to another farmer.
The alarm was raised on Monday morning when Tadgh's wife, Ann, went to a neighbour's home and revealed that shots had been discharged in her home.
When gardaí managed to gain access to the house after 1pm on Monday afternoon, they discovered the body of one of the sons in a bedroom of the house. He had sustained gunshot wounds.
Mr O'Sullivan's remains were found near his other son's body on land near the farmhouse.
Both were shot.
Gardaí are trying to establish who carried out the shootings but have confirmed that they are not looking for anyone else as part of the investigation.
Two licensed firearms, which were recovered from the scene are now being examined.
It is hoped the examination, along with the post mortem results and information from Mrs O'Sullivan, will aid gardaí in establishing the identity of the person who fired the fatal shots.
Gardaí are treating the deaths as a murder-suicide incident.
Yesterday, a cordon remained around the entrance to the property as a forensic examination was conducted by members of the Technical Bureau who arrived at the scene on Monday evening.
An Garda Síochana is appealing to any person who may have any information that may assist in the investigation of the incidents which occurred this morning to contact investigating Garda at Mallow Garda Station 022 31450, the Garda Confidential Line 1800 666 111 or any Garda station.
