8 Years

In 1988, a young man is gunned down on a highway after his car is hit from behind and a woman riding with him is wounded. The case was thought to be a routine carjacking until the woman disappeared from the hospital where she was being treated. In 2006, the probe is reopened when the woman is spotted in Atlantic City and she's brought in for questioning. The investigation reveals that the woman and the married victim were having an affair and planned to run away with each other.
