The biological parents of missing 7-year-old Kyron Horman on Friday accused his stepmother, Terri Moulton Horman, of kidnapping and warned her she will go to jail if she doesn’t cooperate with investigators.

On day 5 in the search for Skyline School second-grader Kyron Horman, authorities still released little information about the case but continued to urge the public to help them through tips.
