This Is Part 1 of 2 On The Mysterious  Disappearance of 7-Year-Old Kyron Horman Who Went Missing in Portland, Oregon On June 4, 2010.On the morning of June 4, 2010, Kyron Horman went to school with his step-mom, Terri Horman, and his 19 month old half sister Kiara.  It was a big day at school because they were having their annual Science Fair that morning and the school Talent Show that afternoon, both events Kyron was participating in.  After touring the Science Fair and snapping a picture of Kyron standing next to his science project on the Tree Frog, Terri and Kyron parted ways at approximately 8:45 a.m.  This was the last confirmed sighting of Kyron.  After Terri allegedly watched Kyron walk down the hallway towards his class, he seemingly vanished into thin air.  Since then, rumors have swirled around Terri has having had something to do with Kyron's disappearance, but she has never been officially named a suspect.  This hasn't stopped Terri from being vilified by the community and the media.
