Robert DeValley was a constable in Ireland. When Jerome Khan informed him of him of the disappearance of his girlfriend Imogen Frazer on Fleming's Island in December 1981, DeValley took Khan, Donal Dineen and Aoife Dineen to the island to search for Frazer.
DeValley owed money to some people, so he planned to copy the I onto a disc and take it to the mainland to influence the stock market to his advantage. However, when he tried to escape the island in a helicopter, the I Predator, drawn by the sound of the helicopter engine, attacked the helicopter. The attack killed DeValley and the pilot.
