Examining the fentanyl crisis in St. Louis through interviews with former addicts, families and those pushing for change.

Along the street of Horseshoe Lake Rd, you will find a small building that looks abandoned in Granite City. Inside is not much, but it is a place athletes from both sides of the river can call home. It is a facility for baseball players and boxers, but it is also home to Elite Speed.

Maurice “Duke” Harris can only shake his head when he thinks about his big sister Barbara, who everyone called BeeBee. Nearly 30 years ago, she was brutally murdered in her north St. Louis County home in a case that appeared to have plenty of evidence, only to turn ice cold as the days ticked by. Harris doesn’t have to look far to remember his sister. Her belongings still reside in his basement. A basement he can still barely enter without breaking into tears.

In 1992, a lone gunman shot and killed six people in five cities along Interstate 70. The killings happened within one month and then he suddenly stopped. He later became known as the I-70 serial killer. Then in 1993 and 1994, three women were shot using similar methods at shops near interstate in Texas. Two of them women died, but one survived: Vicki Webb.

Thousands of you tuned into our special series, “Chasing the I-70 killer.” Now, as police await the results of DNA evidence, we take you behind the scenes of News 4’s pursuit of a serial murderer. We traveled more than a thousand miles to track the killer, speaking to more than 20 people in five cities.

In the final episode, investigators look at similar killings that could be linked to the I-70 spree, and one victim in Texas tells her story of survival after being shot by someone who may be the serial killer.

The I-70 Killer strikes in St. Charles, killing 24-year-old Nancy Kitzmiller and starting a local investigation that detectives haven't let go for 30 years. Now, even after all that time, St. Charles police are leading the hunt for the murderer as retired detectives and new investigators outline why they refuse to let the case go cold.

The investigation heads to Terre Haute, Indiana, where investigators try to make sense of why the killer claimed his only male victim. Then, in Raytown, the last witness able to talk about the killer gives his harrowing story of pulling his own gun and what he wishes he had done differently.

As those closest to the initial killings re-live the experience, new clues emerge as to how the killer could come and go from each murder scene without being noticed.

A man killed six people in 1992, appearing out of nowhere to strike in broad daylight before disappearing just as fast. Now, nearly 30 years later, police from throughout the Midwest think they can finally catch him, and News 4 is going along for the chase.
