In April and May of 1992, six people were tragically killed in three Midwestern states.

The victims were all working in specialty shops near Interstate 70 and Interstate 35 when

they were shot in the back of the head execution style.

Notably, the killer only robbed the stores of small amounts of money and often left the

other cash behind.

Initially, no one realized the connection between the murders, assuming they were all simply

failed robberies.

However, after various police departments began sharing information, they identified similarities

amongst the cases.

The department started working together, and eventually, the listics has confirmed the

same firearm and ammunition had been used in all of the shootings.

It's been more than 30 years since the I-70 serial killer began his reign of terror,

and investigators are still searching for the man responsible.
