THE BRONX - A Bronx school has suspended classes for the day in honor of one of the seven passengers killed in an Amtrak train derailment in Philadelphia Tuesday night. 

Derrick Griffith, a Bronx native and pioneer of education, was the founding principal and director of CUNY Prep High School. He launched the transitional program back in 2003 to help prepare students between 16 and 18 years old for college. 

Many students tell News 12 that they don't know where they'd be without the school, and are forever grateful to Griffith. 

The 42-year-old had moved to Brooklyn where he worked as dean at Medgar Evers College. He leaves behind his mother and 23-year-old son, who both still live in the Bronx.
