Dr. Jennifer Bengston addresses members of the media March 28 at the Lincoln County Sheriff's Office. Bengston, an anthropology professor at Southeast Missouri State University, with the help of her students, assisted law enforcement in identifying Jack Langeneckert, a real estate agent from Florissant who disappeared in 1982, and whose remains were found on a farm in Lincoln County in 1984

It is a mystery that is four-decades-old and has begged the question: What happened to the well-dressed real-estate agent Jack Langeneckert of Florissant who was headed to work in 1982? Not many answers other than he was 50-years-old at the time he went missing after leaving home to go show a piece of property. 

Two years later, after his disappearance skeletal remains were discovered in a farm building in Lincoln County in June 1984. The cause of death was a gunshot to the back of the head.
