Santa Fe, New Mexico
All that is known about William's life is that at some point, he met Ofelia Salazar and fell in love with her, eventually prompting him to propose to her. However, after an unknown period of time, their engagement was broken.
In a flashback, William and Ofelia are enjoying lunch at a seaside restaurant in Rosarito. After the waitress clears their table, she brings out two glasses of water, one containing a ring in which William proposes to Ofelia. He also asks her to move to Santa Fe with him as he starts a new job. While Ofelia is hesitant, she is excited and agrees to talk to her mother about marrying William.
As the city of Santa Fe quickly fell to the undead, William's fate remains unclear. It is unknown whether he was able to survive the outbreak or was killed and/or turned into a zombie.
