In 2014, Evans and his family appeared on an episode of the Travel Channel's Ghost Adventures. The show's paranormal team, led by host Zak Bagans, visited Evans' house in Oklahoma, which he claimed to be plagued by Zozo. During interviews, he added new details to his original story, including the temporary blinding of his daughter, which he blamed on the demon.
In 2016, Evans co-authored a book, The Zozo Phenomenon, with leading paranormal expert Rosemary Ellen Guiley. He once again added new details about his first encounter with Zozo, claiming that he came in contact with Zozo in 1982 after discovering a Ouija board in his then-girlfriend's basement. Engraved on the back? "ZOZO."
According to The Paranormal Scholar, earlier that year in a phone interview with a New Jersey newspaper, Evans told the same story about a mysterious Zozo-engraved Ouija board, only that time, he claimed "Zozo" was written on the front, "where 'Ouija' is normally written," not on the back. Both of these mentions were the first time in the seven years that Evans had been talking about Zozo that he mentioned an engraved board.
