A former convict who spent eight years in jail is telling the story of ex-cons who turned their lives around. In 1995, El Sawyer was living in Lancaster selling drugs and shot a man who stole packets of crack cocaine from him. He is out of prison but still on parole. Sawyer now is a filmmaker and youth mentor. He will be at Millersville University Thursday screening his moving “Pull of Gravity.” The movie will be shown at the Ware Center at 11 am. A second showing will be in the Clair Performance Center at 7 pm.
