Aiden O'Malley was an associate of Derrick McReary. At some point prior to 2008, Aiden was arrested for a string of robberies. Aiden blamed Derrick for his conviction and his friend Bucky promised that he would take out McReary's family.
Some time later, in the late 2008, Derrick orders Niko to break Aiden out of jail and then execute him in northern Westdyke, Alderney. When about to be killed, he will shout about how he doesn't want to die and that he thinks Derrick is a rat.
The ghost is believed to be located around the northern Alderney cliffs where he was executed. After several investigations, myth hunters have reported hearing strange noises but no sightings have been made. For these reasons, the myth is considered unlikely.
