The inquest into the deaths of a family in Co Cavan has heard that Alan Hawe, who murdered his wife and three sons before taking his own life, had been suffering from a severe mental illness.
Professor Harry Kennedy, who carried out a report for the coroner based on Mr Hawes' medical records and suicide note, said he had progressed from a long standing depressive illness to a severe depressive episode with psychotic symptoms.
Clodagh Hawe and her sons, Liam, 13, Niall, 11 and six-year-old Ryan were found dead on 29 August last year.
