School Superintendent David Hornbeck said yesterday that he would seek a ``full investigation'' into allegations that a teacher smoked crack cocaine in a classroom at Benjamin Franklin High School.
The teacher, Caleb Jackson, 41, who lives in the 2300 block of North Colorado Street in North Philadelphia, on Friday was charged with possession of narcotics.
Police said they were summoned to the school by Principal Tilghman Moore after Jackson was discovered inhaling from a pipe inside Classroom 305 Friday morning. A nonteaching assistant said Jackson had dismissed his students early and when the assistant entered the room, she smelled crack cocaine, according to Sgt. John Dougherty of the Ninth Police District.
