'The Covina-Valley Unified School District is shocked by the Orange County District Attorney 's decision with regards to the charges filed . 'However , we recognize that the investigation is continuing and additional charges could be forthcoming , ' spokesperson Michelle Van Der Linden said in a written statement . 'As teachers and administrators who work closely and in a trusted position with children , we hold ourselves to a higher standard . 'We are subject to the Education Code and our Board policies and as such , we will continue with our own investigation and have created our own draft statement of charges for dismissal , which will be delivered to both individuals . ' Lippert , who allegedly organized the trip , was charged with unlawful sexual intercourse and furnishing a controlled substance to a minor , both felonies . Ghirelli now faces charges of unlawful sexual intercourse , furnishing a controlled substance to a minor and oral copulation of a minor , all of which are also felonies . Prosecutors had initially said there was not enough evidence to file sex abuse charges . Ghirelli 's lawyer said the teacher intends to 'vigorously defend ' against the charges , telling the Los Angeles Times : 'There 's two sides to every story . ' The teachers , from South Hills High School in Corona Valley , California , allegedly went on a camping trip to San Clemente Beach with five students from December 27 through 29 . Lippert , who has taught as a teacher for the Covina-Valley Unified School District for 15 years , had previously met up with a group of male students from her high school at a beach in San Clemente last November , on a trip that was not school sponsored , according to KCAL-TV . In initial reports , Lippert had reportedly given the group alcohol and then engaged in a sexual act with one of the students , according to Los Angeles County sheriff 's deputies . She then made plans to meet up with the students for a second liaison at the same spot , bringing along Ghirelli , who has been teaching for the district for five years . The pair then met up with five students of the same group on the non-school sponsored camping , spending a night on the beach .
