Skyline Elementary School in northwest Portland Oregon is having their annual science fair so the school is opened about 30-minutes earlier than normal to allow parents and students to see the different projects created by the students. Arriving at Skyline just after 8 a.m., Kyron Horman and his stepmother, Terri Horman, go to his classroom and drop off his coat and backpack. Kyron then shows his stepmother his exhibit called "The Red-Eyed Tree Frog".

The two walk around the classes looking at other students' projects and see many other parents and children who have arrived early for the science fair. Terri Horman volunteers her time helping Kryon's teacher, Kristina Porter, and Porter sees Kyron and Terri Horman in Kyron's classroom that morning and another teacher sees Kyron and Terri in another classroom before the 8:45 a.m. school bell rings

As Terry Horman leaves the school, she sees Kyron walking down a hallway toward his classroom inside Skyline Elementary. Kyron has already placed his bookbag and coat in Miss Porter's classroom when he first arrived for the science fair. Miss Porter starts her class as like every day, then reading group, then recess, then lunch. Around 3pm the children, tired from a busy day, get on the bus to go home.

Kyron Horman's father Kaine is at home getting his daughter ready to meet Kyron's bus after school. When Kyron doesn't get off the bus, Kaine Horman assumes there is confusion and Kyron is waiting to be picked up at school. The bus driver calls the school to see if Kyron is waiting to be picked up and finds out from the front office that Kyron has been marked absent, he hasn't been at school all day.

Investigators build a timeline quickly as they search for Kryon Horman. The 7-year-old arrives at school with his stepmother, Terri Horman, around 8 a.m. for the Science Fair. Kyron and his stepmother see teachers and other parents touring the classes, and Terri Horman says goodbye to Kyron in the hallway that goes toward his classroom at 8:45 a.m. near the south entrance of the school. Investigators say Kyron is seen by one more person around 9 a.m. but they will not identify the individual.
