The DOE's background checks must not be very in depth if they hire a guy who was booted from the Marines and NYPD on psychiatric grounds. He also threatened to "chop" his mom and sister into pieces. After killing the girl jogger by the Belt Parkway he went back to his job as a para at PS 200 in Brooklyn the very next day. Unreal!!
