Daniel Costigan

Daniel Costigan (1911–1979) was Commissioner of the Garda Síochána from July 1952 until February 1965. Costigan was the second, and final, civilian commissioner of the Garda Siochana.

Personal life He and his wife Hilda had three daughters and three boys. He was widowed in 1966. Three death threats had been received and Commissioner Costigan warned his subordinates to not disregard the possibility of any such threat, no matter how implausible the source.

Criticism by Murphy Report The Murphy Report criticised Commissioner Costigan for his handling of allegations of child abuse by Fr. Edmondus (pseudonym). Scotland Yard had contacted him concerning images that the priest had sent to be developed in the UK. Commissioner Costigan asked Archbishop John Charles McQuaid to handle it because a priest was involved and he claimed "Gardaí could prove nothing".
