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.
The Los Angeles Times ( http://lat.ms/zjLyxv) reports that when the third investigation was completed, Hernandez quit teaching in Los Angeles and started working for the Inglewood Unified School District.
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.
