Post-mortem examinations on three brothers who were found dead in Co Cork yesterday have been completed.
Nine-year-old twins Thomas and Paddy O'Driscoll were found stabbed at their home at Deerpark in Charleville yesterday evening.
Gardaí are not looking for anyone else in connection with the deaths of the two boys but they are appealing for witnesses to contact them.
Their 21-year-old brother Jonathan was later found dead by the bank of a river in Buttevant, around 15km from the family home.
Foul play is not suspected in his death.
The boys' parents, Helen and Thomas, were comforted by family members and friends as the bodies of the twins were removed in two hearses.
The Deputy State Pathologist Dr Michael Curtis completed his preliminary examination at the scene and carried out the post-mortem examinations at Cork University Hospital.
Gardaí have said that for operational reasons investigating officers are not releasing details of the post-mortem examinations.
Funeral arrangements for the three brothers will not be finalised until their bodies have been released to the O'Driscoll family.
It is possible it could be Monday before the funeral mass and burials take place and it is not known yet if the three brothers will be buried together.
The twins attended Banogue National School and were in third class.
The school has issued a statement paying tribute to the boys and stating its shock and sadness at their deaths.
"This is a terrible tragedy for the family, the school and the whole community. We are deeply saddened by this event," said principal teacher Sheila Cagney.
"Our sympathy and thoughts are with the family and friends at this terrible time," she said.
Ms Cagney described both boys as loving, energetic and full of fun. The boys had been pupils in the school for just over a year.
She said the focus of the staff at this time was on the pupils in the school who are trying to come to terms with the loss of young friends.
"We will help the children to the best of our ability," said Ms Cagney.
"We are receiving support from the National Education Psychological Service who will be at the school today to support staff on dealing with the tragedy."
