I just found out two weeks before Sodapop's 19th birthday he passed. I didn't believe it at first, but searched into it for almost three hours and found that indeed he was drafted after The Outsiders book. He was killed in the Vietnam War September 25th, 1967. S.E Hinton told Rob Lowe before filming The Outsiders to help with his acting. He said it affected his performance. I cried my eyes out for like an hour. He will be missed.
