SEASON 2, EPISODE 209 - The body of a woman who has been missing since 1985 is discovered in a wildlife preserve. The victim was shot through the heart. The detectives interview her daughter, who was 12 years old when the woman went missing. The daughter's abusive father is also dead, but the team believes he could have been responsible for the murder--until eight more bodies are found in the preserve. The detectives theorize that the murderer abducts his victims, takes them to the preserve then makes them run for their lives while he hunts them. But once the hunter is found, will the detectives be able to make an arrest? Recurring guest star Nicki Aycox appears as Rush's sister, Christina.
