we had no body, we had no actual gun. we knew what the past history was between ron harshman and melvin snyder, and common sense will tell you, yeah, he has good reason to want to kill melvin snyder. he is the only person that we know of that ever wanted to harm melvin. but that doesn't prove it in a court of law. >> before his disappearance, melvin snyder told friends that he was afraid of ron harshman because ron was still angry about the affair he had with his wife. >> always have a strange feeling about the fact that he, in essence, had predicted something like this was going to happen. >> for the next 15 years, the case haunted prosecutor jack nelson. he knew melvin snyder personally. and something just didn't add up.
