Here's what www.netflix.com says:
The Rockville Slayer(2004)
A lonely deputy named Charlie Fisher (Circus-Szalewski) is about to have his predictable world turned on its ear when a series of multiple murders -- involving Charlie's brother as one of the victims -- rocks the foundation of his small town. It seems that the last random murders happened 29 years before. Could this violence be part of a pattern?
The storyline was sorta hard to follow. The murders at the beginning had NOTHING to do with the murders that occurred 20 years before. And there was a random man at the end that I never did figure out who he was? It was ok, but just random. Not a easy to follow storyline.
