Alan was a plastic surgeon. He was married to Sarah Cardwell, but had an affair with a singer named Samantha Warner. According to his wedding ring, he and Sarah were married on August 5, 1982, which would mean that Alan and Sarah were together for 30 years before Alan's death. Alan had black hair and green eyes, and wore a sky blue shirt with a white lab coat.
Alan was stabbed in the stomach by a candlestick and was left to die in an alley. Nathan discovered during the autopsy that Alan died fighting with his killer. Alan officially died from a punctured liver and shards of glasses were found in his hands. This proved that the killer wore glasses and then stuffed a piece of paper down Alan's throat.
