A Devil in the Valley

This is a true story.

In 1994, an aspiring young cold case investigator in California’s East Bay, Paul Holes, puts aside trying to solve the Golden State Killer case as he waits for science to catch up.

Paul returns to an old file cabinet at the back of the forensic lab to look for another cold case he can work—something with DNA. He finds one. The 1978 murder of a married mother who went for a morning jog in a nearby park. The original investigators believed that a serial killer named Phillip Hughes was responsible; they just couldn’t prove it. But Hughes was headed to prison for three other local homicides, all because of an unexpected break in those cases. Without it, Hughes might have gotten away with everything. In the years since though, as Hughes sat in prison, so did his secrets. And now he’s coming up for parole.

In a race against time, Paul commits to solving the 1978 cold case before Hughes is let out. The victim’s family needs an answer. And, if Paul can prove that Hughes is the killer, he’ll use it as leverage to force Hughes to confess to everything else he may have done.

Little does Paul know, however, that the 1978 cold case he opens will take an unexpected turn, lead to other cases and killers he never knew about and haunt him for his entire career. It turns out that the small towns of Contra Costa County were home to a more sinister history than anyone had imagined. But the clues didn’t disappear. They just needed the right person, at the right time, to see them.
