The mother of an 11-year-old girl who died after an incident in their home is in intensive care.
The woman, named locally as Dr Bernadette Scully, was rushed to the Midland Regional Hospital in Tullamore, Co Offaly, on Saturday night.
She had been discovered with her daughter Emily, who had a disability, unconscious in the family home. Gardai said they are not seeking to interview anyone else in connection with the girl's death.
A post-mortem examination was carried out on the girl's body in the hospital but proved inconclusive.
Amid suspicion that medication may have been involved in her death, toxicology tests are to be carried out but it may be several weeks before the results are known.
It is understood gardai will wait to interview the 54-year-old woman. She works as a GP in the Clonminch medical centre in Tullamore and was well known and respected in the town.
Local representatives who declined to be named said the entire town had been left in extreme and complete shock over the death.
It is believed she was separated and had just one daughter.
Gardai said the girl was found in the house in the Bachelor's Walk area of the town. An ambulance had been called to the home at about 9pm and gardai also attended the scene. Both the mother and daughter were taken to the hospital in Tullamore where the girl was pronounced dead.
The Garda Technical Bureau spent time at the house carrying out forensic checks while State Pathologist Professor Marie Cassidy was called in to conduct the post-mortem examination.
