Kyron looks like such a nice young kid, and the science project he was pictured in front of appears really complex for a six year old -- and Terri Horman's story never made sense; I hope this enigma is solved quickly.
KATU.com Mobile Edition -- DHS opened a case on Kyron's stepmom years ago
"......A source confirmed late Sunday afternoon that the Oregon Department of Human Services opened a case on Terri Horman following a 2005 arrest and charge of driving under the influence. Her biological son, who was 11 at the time, was in the car when his mother was arrested. As such, Horman also was convicted of reckless endangerment of that son. Horman pleaded guilty in that incident. She had her license suspended for a month and a half, and served out a 12-month probation for those convictions."
