NEW YORK, Nov. 15 (UPI) -- E-mails expressing hatred for a missing Oregon boy suggest his stepmother "could have hurt him in the worst possible way," the child's biological mother says.
Desiree Young told NBC News she believed her ex-husband's wife, Terri Horman, was withholding information about the disappearance of Young's son, Kyron Horman, who would now be 8 years old.
After Portland police shared the e-mail and text messages with her on Friday, Young told NBC she is convinced more than ever that Terri Horman was involved and holds the key to solving the mystery.
"It's very clear from Terri's horrible words that she had a severe hatred for Kyron," Young said.
Police have not named Terri Horman a suspect in the case, and she has not been charged in the disappearance of Kyron, last seen at a school science fair Horman drove him to on June 4.
"She blamed a lot of the marital problems between (Young's ex-husband) Kaine and herself on Kyron; it was a huge point of contention in their marriage," Young told NBC. "She had expressed in great detail her hatred of Kyron.
"I now believe, without a shadow of a doubt, that not only is she capable of hurting Kyron, it is clear that she could have hurt him in the worst possible way."
