In 1992, a store clerk was found shot to death in broad daylight at the Boot Village in St. Charles, Missouri. Nothing was stolen and there was no sexual assault. This bizarre and seemingly isolated murder was quickly connected with others in Indianapolis, Wichita, Terre Haute, and Raytown. The media dubbed the suspect "The I-70 Serial Killer." He has never been captured, and the story quickly fell out of the media's attention. But the cases never went cold for the officers in those cities.In 2021, with the advancements in DNA, St. Charles Police Captain Raymond Floyd launched a task force, bringing all jurisdictions together along with federal agencies to take one final crack at solving the crimes. The task force selected Bob Cyphers of KMOV-TV to follow them along, city by city, in the hunt for the killer. Cyphers and his KMOV crew produced a seven-part award winning series called "Chasing the I-70 Serial Killer." Their work led to national exposure of the case in People magazine and on the Discovery Channel, winning an Edward R. Murrow Award and being nominated for an Emmy.Dead End: Inside the Hunt for the I-70 Serial Killer follows on the work done by the task force with the important goal of keeping the story alive in the public eye. New evidence, never before available to the public, is revealed here, with the hopes of triggering a memory or revealing a new lead. The task force may be closed, but the drive to find this killer is alive and well.Anyone who may have information about the case should contact the I-70 hotline at 1-800-800-3510.
