For years, someone has been killing prostitutes on the same day of the same month; in their business room. However, the first one was a mistake. All of the killings were in the state of California with the exception of one that was in Las Vegas. The first one was just a weary traveler that just wanted a place to sleep for the night before seeing her son and daughter-in-law the next day. For years, the Bakersfield Police Department tried to solve the case but to no avail. Soon, the highly successful Cold Case Investigators, or CCI, were called in to help solve the killing of Denise Robinson. Soon the lead of CCI investigator, Patrick Johnson, a retired U.S. Air Force Security Police Investigator found move victims of what was soon to be called The Prostitute Killer. Even though he eventually thought he knew who did the killings, along with an accomplice, it was not until the killer and accomplice died in a murder-suicide act.
