About this episode

John interviews retired Detective Sergeant Martin Egan about crisis negotiation and a specific case in Co. Donegal.

In this episode of Lines of Enquiry: Case Notes, John is joined by Martin Egan, retired Detective Sergeant with An Garda Síochána. Martin spent 30 years in the force and was also trained as a Garda crisis negotiator. He reflects on the communication, patience and judgement required in critical incidents, where the aim is to bring people to safety while working as part of a wider Garda response. Martin also speaks about the case involving Jasmine McMonagle in Co. Donegal in 2019, where he was part of the response team that arrived at the house and negotiated with her killer. He discusses the difficult decisions made that morning, the importance of protecting the children in the house, and how gardaí deal with the most challenging parts of the job.
