He also is “a proctor at Topaz and a volunteer at Hesperia High School, but is no longer an employee of the district, and he is not allowed on any district site,” the Hesperia Unified School District said in a statement.

Dance classes were being held Monday night at the Hesperia studio.

Parents, however, said they were not interested in commenting.

“I was advised that we have nothing to do with what he did. He no longer works with us,” one man said outside the studio.
