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.
