Martin was attending a party at a student house, when it was gate-crashed by zombies.
He attended the party on Gabalfa Road with a group of friends, including Jace and Hayley. When a man burst in and bit into Hayley's forearm, Martin and Jace grappled him to the floor then, with the help of four other partygoers, locked him in the cellar.
When Andy Davidson and Dawn Stratton arrived to investigate the incident, Martin gave an account of what had happened, before the pair entered the cellar to apprehend the perpetrator. Andy and Dawn arose from the cellar to find the house being attacked by zombies.
Martin was a gangly, bearded youth.
