Hanson was a runaway from Pocatello, Idaho who appeared in "Organ Grinder".
He lived on the street with his sister, Gracie. They knew other runaways who had disappeared, and over dinner with Nick Burkhardt and Juliette Silverton told them when they had last seen their friends Steven Bamford and Kevin Standish and that they had not heard from either of them since. After Gracie told Dr. Levine about helping a detective who was investigating the disappearances, Geiers abducted Gracie and Hanson. Hanson left a trail of puka shell beads to the makeshift operating room which Nick and Hank followed. Doctor Levine, who also proved to be a Geier, was about to remove Gracie's organs when Nick and Hank rescued Hanson, Gracie, Kevin and the others.
His name is a play on Hansel from "Hansel and Gretel"
