LOS ANGELES -- A substitute teacher in the nation's second-largest school district was investigated three times for sexual misconduct with students before he quit in 2007 to work for a neighboring district.
George Hernandez was never arrested or charged in the Los Angeles Unified School District cases.
He taught there for nearly three years before police found a videotape they say shows him molesting a second-grade girl at school.
The 45-year-old was charged with child molestation but he fled and is a fugitive.
In recent weeks, several Los Angeles school district employees have been accused of lewd conduct.
