Murder One

I found this movie interesting for one primary reason: I am 99% sure it depicts a real event. I went to college in Atlanta, Georgia in the early 1980's, and sometime (I'd guess 1982) in that span, the local news covered this real incident, which I think happened in the 1960's. It had become a current issue in 1982 because the perpetrators were still behind bars, and I think the debate over the death penalty was involved. From what I remember of both the actual event and the movie, it follows the true story reasonably well. I certainly got the impression that the incident was a gruesome as the movie depicts it.
