Its about a woman who killed her brother by cutting his brake lines on his race car. He ran off the cliff n died. This cop appeared home looking exactly like her brother knew every little info to fool her just so she confessed on murdering her brother for the heir of diamond mine. What is the name of the movie please? I've seen it once on a old dish network call primestar and never caught that movie again. I do not know who even played the main characters.

Chase a Crooked Shadow (http://www.imdb.com/title/tt0050246/)
