John arrived at the Nuremoh family home after Edward Nuremoh and Lola's deaths. He attempted to kill Tess by ramming his car into hers. Tess, confused and estranged from Dick Tracy, was enchanted by him and didn't press charges.
Tess went along with John and invested in his business of stealing dogs and reselling them. She soon began to feel guilty and started to return the dogs behind his back. He found out and tried to get his dog with steel fangs to attack her. It turned on him and ripped out his throat. Tess was held briefly on murder charges but was eventually released.
