I saw this case on Unsolved Mysteries a long time ago and I'm trying to remember what case it is. A man raped his sister in law. He blindfold her and put her in his car on the floor of the passenger seat. The victim recognized that it was her brother in-law. I can't remember if he murdered her or not but he was caught and went to prison. He would up escaping and went to visit his kids one time and disappeared. I believe this case happened in the 80s and I saw it on UM in the 90s.
