In this episode, retired agent Jonathan “Jonny” Grusing reviews his investigation into the activities of former FBI informant Scott Kimball, who has confessed to being a serial murderer. Grusing worked with the BAU, the FBI’s profiling unit, and numerous law enforcement agencies to bring homicide charges against Kimball and recover three of his victims from remote, mountainous areas.
Kimball was an FBI informant who manipulated law enforcement for twenty years, bringing investigators into his homicides while he learned about how the justice system worked. He has claimed to have murdered from 20 to 50 people, officials may never learn the truth. The details of his murders are horrific, revealing his deception, complete disregard for human life, including family members he claimed to love. Grusing continued the investigation following the sentencing to identify more potential victims of Kimball throughout the western United States until his Bureau retirement.
Grusing served in the FBI for 25 years. During his career, he worked violent crime, to include bank robberies, kidnappings, missing persons, serial rapists, serial killings, and special jurisdiction homicides.
In 2008, Jonny Grusing was named as the Behavioral Analysis Unit (BAU) Coordinator for Colorado, consulting on difficult or unusual homicides or missing persons cases throughout the state.
He is currently the Director of Safety and Security for the Douglas County School District in Colorado and managing his own investigative consulting service. He is writing on a book about his time spent with Scott Kimball while working on this serial murder case.
“So I go down and collect the cranium and collect the skeletal system and send it all to the FBI lab. I get Lori’s DNA and send that in. They do a cross section of the femur and guess whose DNA it was?”—Retired Agent Jonny Grusing
