Calaveras Unified School District Superintendent Mark Campbell said at least two therapy dogs and 10 counselors were on hand for students, teachers and staff to guide them through the grieving process.
Campbell said he met with Leila's parents Monday when they came to the school to thank teachers and staff for the support they had offered.
The parents were at a Little League game at the time their daughter was attacked, Campbell said. Leila's brother found her and notified the father, who called 911 and went home, he said.
Part of the school-guided grieving process included classrooms taking turns writing notes to Leila and hanging them on the fence at the entrance to the school. They came in somber groups and attached their notes one by one.
"Dear Leila: You were a fun person and very smart. I enjoyed being around you every minute," one girl wrote.
"I know you are in heaven looking down at us but you will always be in my heart," wrote another.
Campbell said officers will have a presence at the school at until the case is resolved.
The suspect is the subject of a broad manhunt by the sheriff's departments of Calaveras and surrounding counties, the California Highway Patrol and the state Department of Justice. Sheriff's officials say investigators collected fingerprints and what they believe is DNA from the home on Sunday.
"Our normal has changed and we will move forth and heal by coming together, as we all are here today," said Linda Stoes, whose daughter dressed in purple Monday to honor her friend. "Our perspectives have changed forever."
