Continuity mistake: When the "substitute" boy gets off the train he is with an older women. The reporters ask the mom and boy to take a picture together. You can see from the camera angle that the older woman is in the background when the flashes go off taking the picture. Later in the movie, the psychiatrist holds up a newspaper article with the picture in it. In the newspaper picture, the older woman is not in the background.
Christine Collins: I used to tell Walter, "Never start a fight... But always finish it." I didn't start this fight... But by God, I'm going to finish it.
Answer: No. He was murdered at age nine. The movie uses creative license to bring up the suspicion that he could have somehow survived to create a dramatic hope in the end. Moreover, the killer was very unstable and retracted his testimony more than once. There is no solid proof of the boy surviving the killings. The police even found partial evidence of Walter Collins at the burial site. See the Wikipedia article for more information.
