This will probably prove to be a radio hoax but the radio program I listen to has been taken calls from a caller who sounds legitimately upset but makes the following claims: When he was 14 and his sister was 15 they were put in fostercare. They were sexually abused by the fosterparents. The sister committed suicide very shortly after the abuse began. Seven years later the caller supposedly killed his abuser. This would have been 1983-1987ish. Supposedly the body was never found. This "missing person" would have been a middle school teacher and/or coach. Possibly 5 foot 6, 160lbs. Ring any bells for anyone?
