PORTLAND, Ore. — Several people saw Kyron Horman leaving Skyline School with his stepmother the morning he disappeared, according to a newly released book.
Author Rebecca Morris' new book, "Boy Missing: The Search for Kyron Horman," claims Kyron's regular bus driver, along with a classmate and two of the classmate's family members witnessed Kyron walk through the school parking lot with Terri Horman and her infant daughter on June 4, 2010. The second grader was never seen again.
Horman, Kyron's stepmother, has long been the focus of investigators but never been arrested or charged in connection with the boy's disappearance.
The new book by Morris, a New York Times best-selling author, is being released almost exactly 10 years after Kyron's disappearance. Morris relied heavily on extensive interviews and notes provided by Kyron's biological mother, Desiree Young, and other people close to the case.
"You can't do a book like this without having family cooperation," Morris said. "I wanted to tell the story of how Kyron's disappearance affected a community because there are all these really fascinating people who became part of the story."
Kyron Horman was last seen at Skyline School in Northwest Portland on June 4, 2010 after attending a science fair. The second grader's disappearance prompted the largest search-and-rescue operation in Oregon history. He has never been found.
Investigators quickly zeroed in on the stepmother, Terri Horman, who seemed suspiciously cheery and upbeat the day Kyron disappeared, Morris wrote.
The book described how Terri Horman washed Kyron's jacket and backpack the day he disappeared.
Additionally, Morris explained detectives outfitted Kaine Horman, Kyron's father with a wire to record conversations inside the family home, where relatives, including Terri Horman, had gathered. Morris also said police placed a tracking device on the family's truck. Kaine Horman was not involved in the book.
"Boy Missing: The Search for Kyron Horman" details the alleged circumstantial evidence surrounding Terri Horman, including claims she had emailed a friend the day before Kyron disappeared, saying she planned to leave Kaine and her marriage the next day and take her infant daughter with her.
The book recounted the stepmother's movements on June 4, 2010, including buying cold medicine and other grocery items at Fred Meyer stores. The author claimed items purchased that day, including a bottle of Motrin, were never found.
Terri Horman struggled to explain her whereabouts during a portion of the day on June 4, 2010, according to the author.
The book also raised questions about an unexplained injury on Terri Horman's leg, a good sized gash below the knee. Horman said she dropped a weight on her leg at the gym.
Terri Horman declined to speak with Morris for the book and was not available for comment.
The Multnomah County Sheriff's Office would not confirm the information released in the book. Investigators have described the case as an active, ongoing investigation.
