Just had to review because somebody else complained about how they wasted their time since it never revealed the killer. If you're an educated person on this case or cases in general, this was a real case, which was never solved, so the movie doesn't just make up an ending. A confirmed identity isn't there because there never was one in real life. The movie was well made and had an amazing cast definitely a good watch for anybody interested in REAL cases and/or UNSOLVED cases.
