Origin
Jack was once a happily married man. Tragedy struck when his 3-year old daughter fell from the balcony on the thirtieth floor of their New York apartment, while his back was turned on her. His wife left him and Jack eventually moved to the quiet town of Slivercreek, Colorado. There he encountered Snowman for the first time. While trying to get away from the snow demon, he met Gwynn Fiala.
