BBC reporter Laura McDaid held Martin Barry's hand as he died at the Dignitas Clinic. 17 years later, she begins a search to fulfil his last request: to find his birth mother and pass on a message.
To move forward with the search, Laura first needs to explain why it's taken her 17 years to have the strength to search for Martin's mother.
She takes Kerry back to the aftermath of Martin's death, and how it was handled by the press at the time.
Will the records provide her with any further information?
