Shawn was a teenager who died while in high school, and is the subject in the Season 9 Episode Ghostly Confessions.
Shawn and another friend climbed up a local water tower in New Haven, and his friend slipped and fell to his death. Shortly after his friends death, Shawn became depressed and most likely took his own life. His identity was revealed later when Paranormal Investigators Kurt Knapp and Karen Hollis were called to investigate the haunting that have been going on. His spirit latched on to Macy feeling that she was his mother, due to the fact that she looked like her mother Carrie who knew Shawn and attended school with him. Kurt suggested that the family should make him feel welcome as he was looking for a family and cross over when he was in peace. As he meant no harm to the family.
