Newly released notes of a California elementary school principal have revealed that a teacher charged with molesting kids in class blindfolded a second-grader and put something in her mouth.

Tests by the Santa Clara County crime lab found semen on chairs in the San Jose classroom of 35-year-old teacher Craig Chandler, who was charged earlier this year with assaulting five children at O.B. Whaley Elementary School.

The law requires principals, teachers and others who come into contact with children to report suspected child abuse.

Vijayendran, 36, was charged in July with a misdemeanor in the case for failing to alert police about the incident. If convicted, she could face up to six months in county jail.

According to Vijayendran's handwritten and typed notes, the second-grade student told her that Chandler blindfolded her and gave her something to drink while the two were alone in a classroom.

The 35-year-old man wiggled her body and head 'back and forth' and asked the child to 'open her legs,' the notes state.

Prosecutors said that rather than report the potential child abuse right away, the principal contacted an official at the school district's human resources department, who subsequently warned Chandler not to conduct what he called a 'Helen Keller lesson' with students alone.
