The PSNI eventually revealed that McGuigan had been "spoken to" by the police as part of the Davison investigation but only "as a potential witness, not a suspect". A 2021 inquest hearing was told that detectives had not considered Mr McGuigan a suspect in Mr Davison's murder, though the inquest's report added that "others" did. McGuigan's son Pearse subsequently insisted that had "the police acted and published the information they have, it would have dispelled the rumours in the community and saved my father's life."
