Det Supt Fox (56) – a married father of three from Seabury Glen in Malahide, Co Dublin – was the lead investigator into the fatal shooting of David Byrne at the Regency Hotel in Whitehall, Dublin on February 5th 2016.

Noel Kirwan, an innocent man who had no involvement in criminality, was shot dead because members of the Kinahan organisation mistakenly thought that he was connected to the Hutch organisation.
