Former FBI agent reveals how serial killer Scott Kimball used his role as an informant to hide multiple murders in plain sight. Read the shocking true crime case
In a chilling real-life case that sounds like a crime thriller, a former FBI informant was exposed as a serial killer, manipulating agents and preying on victims while working under the federal government’s nose.
His name? Scott Kimball — a convicted murderer who used his position as an FBI informant to cover up a string of brutal crimes across multiple states.
🚨 FBI’s Informant Becomes Its Biggest Regret
Scott Kimball, once trusted as an FBI insider, was sentenced to 70 years in prison in Colorado in 2009 after pleading guilty to four murders committed between 2003 and 2004.
But according to former FBI Special Agent Jonny Grusing, the actual number of victims may be much higher.
In an interview with Fox News Digital, Grusing shared:
“He made a game out of tricking the FBI… putting things in our files while making people disappear. It was beyond anything I’d seen.”

🎭 Master of Deception
Kimball had a long criminal history, including fraud and identity theft, even before the murders began. While behind bars for fraud, he manipulated the system by turning in his own cellmate, Steve Ennis, suggesting Ennis was planning to harm witnesses.
That tip got Kimball credibility with the FBI, helping him secure early release — and the title of informant.
But in reality, he was already plotting murder.
💔 The Disappearance of Jennifer Marcum
One of Kimball’s first known victims was Jennifer Marcum, a young woman and former stripper. She was romantically linked to Ennis, Kimball’s former cellmate.
Grusing explained:
“He convinced Steve to introduce him to Jennifer under the pretense of helping her leave stripping. But his real plan was to isolate her — and kill her.”
Jennifer went missing in February 2003, the same month Kimball officially became an FBI informant.
🕯️ Other Victims and Confessions
As the investigation deepened, Kimball confessed to killing:
LeAnn Emry, another stripper
Kayci Mcleod, who was also last seen with him
Terry Kimball, his own uncle

While he was eventually convicted of four murders, he claimed to have killed up to 21 people — and even told his lawyers the number could be as high as 50.
👨👧 Families Fought for Justice
It wasn’t the FBI who caught Kimball — it was the persistence of grieving families.
Two fathers, whose daughters had disappeared after last being seen with Kimball, visited the FBI office and pushed for answers. Their pressure helped reopen case files and ultimately led to Kimball’s arrest.
Grusing admitted:
“Scott left breadcrumbs on purpose. He wanted us to know how smart he was — that he could confess and still get away with it.”
While the remains of LeAnn Emry and Kayci Mcleod were eventually found, Jennifer Marcum’s body has never been recovered.
🧠 A Disturbing Look Inside the Mind of a Killer
Kimball’s ability to manipulate federal agents, exploit legal systems, and gain trust while committing murder makes his case one of the most disturbing in FBI history.
He wasn’t just hiding from the law — he was working with it.
