Kyron, then 7, was last seen on June 4, 2010, when Terri dropped him off at a science fair at his school in Portland, Oregon. She took photos with her digital camera, toured his classmates’ projects, and then said good-bye. Kyron has been missing ever since.
“I am encouraged that Ms. Horman is now willing to make public statements about the events that occurred on June 4, 2010,” Kaine Horman, who officially divorced Terri in late 2013, tells PEOPLE.
He adds: “I hope that Ms. Horman will now cooperate with law enforcement to provide additional information that might lead to the discovery of Kyron.”

A cloud of suspicion has followed Terri since Kyron’s disappearance, though she has never been named a suspect or a person of interest in the case. (Officials for the Multnomah County Sheriff’s Department say it is an “ongoing investigation.”)
To this day, however, Terri insists she did not harm or kill Kyron and has no idea what happened to him or where he is.
“What if? All those what-ifs. What if I had gotten ready faster? What if we had done something sooner? What if I had stayed for the whole fair and not left early?” she wonders. “I wish I could go back to that day and do something different.”
