(CNN) - Tuesday was the first day of classes at the Portland, Oregon, school where Kyron Horman allegedly was last seen in early June. The new year at Skyline Elementary also brings additional security measures to protect the children and staff.
In a letter to parents, Principal Ben Keefer said video cameras will be installed this weekend at Skyline. "These cameras will show external views of the building as well as the main hallway," he wrote. Also, security procedures will be reviewed to ensure they are effective, he added.
Tributes, messages, posters and cards that adorned a "Wall of Hope" for the missing 7-year-old boy were moved Tuesday from school property to a fence outside a nearby fire station, said the Multnomah County Sheriff's Office.
