He was sitting on Aer Lingus flight EI105 from Dublin to John F Kennedy Airport, New York. It was due to depart at 10.55am on April 5 this year.
Edward John Best - who used the aliases John Komori, and John Eum - for social media profiles, thought he had got away with an horrific crime. He was just minutes away from being airborne and on his way back to the US.
