A teacher at Christian High School in El Cajon accused of sexually abusing a child over the course of several years pleaded not guilty Thursday to 14 felony sex crimes counts.

Kevin Conover, 49, was arrested on Tuesday following an investigation into reports that he had abused a minor identified in court only as Jane Doe. The sheriff says the alleged victim was a family member, and one of the charges indicates she was under the age of 10.

Sheriff's investigators were first alerted to the allegations in October, according to the San Diego County Sheriff's Office.

He was booked into county jail without bail and during his brief arraignment on Thursday afternoon, his defense attorneys did not argue for bail to be set.
