The Trail Went Cold – Episode 345 – Gary McCullough and Lena Chapin

May 11, 1999. Barry County, Missouri. 34-year old Gary McCullough vanishes from his farm and his abandoned pick-up truck is found on a rural road five days later. Suspicion is directed towards Gary’s wife, Sandy, who was having an affair with another man named Kristopher Klemp and the couple immediately move in together before they get married. In 2006, Sandy’s 20-year old daughter, Lena Chapin, disappears and is not officially reported missing for years. Since Lena had previously made a tape-recorded confession that Sandy killed Gary and she helped her mother dispose of his body and cover up the crime, investigators believe that Sandy may have also gotten rid of Lena, but since no trace of Lena or Gary can be found, no charges are ever filed. On this week’s episode of “The Trail Went Cold”, we cover the shocking story of two unsolved missing persons cases which took place nearly seven years apart from each other and are likely connected.

If you have any information about the disappearance of Gary McCullough, please contact the Barry County Sheriff’s Office at (417) 847-3121. If you have any information on the disappearance of Lena Chapin, please contact the Dent County Sheriff’s Office at (573) 729-3241.
