A former FBI agent has spoken out about how one of their informants was actually a serial killer and had eluded them for years.
A man who was convicted of killing multiple people was seemingly evading detection in plain sight, as they were able to get away with their crimes while working with the FBI.
Scott Kimball was sentenced to 70 years in prison in Colorado in 2009 after he pleaded guilty to killing four people between 2003 and 2004.
Unfortunately, his actual number of victims could be even higher than that, according to former FBI Special Agent Jonny Grusing.

Grusing also noted that Kimball had repeatedly worked for the FBI as an informant, the agency unaware of the horrific crimes he had committed.
Kimball was also a serial fraudster who had spent stints in prison as both a youth and an adult. During this time, he became adept at understanding and working the justice system as well as manipulating people.
He had even planted the seed of killing witnesses to a cellmate, Steve Ennis, and informed the FBI of his cellmate's 'intentions’ to gain their trust and become an informant.
Speaking to Fox News Digital, Grusing said: “He made a game out of tricking the FBI.
“As long as he won the game in front of him, that’s all that mattered.
“To have someone who enjoyed manipulating us, putting stuff in our files, and then making people disappear was beyond anything I’d seen."
One of Kimball’s victims was the girlfriend of that cellmate, a stripper named Jennifer Marcum.
Grusing added: “Our primary victim in our case was Jennifer Marcum. Mainly, he convinced Steve [Ennis] to hook him up with Jennifer to get Jennifer out of stripping.
“So, at the same time he's making Steve look like the bad guy, he's taking Jennifer and isolating her and killing her.”
By February 2003, Kimball was considered an informant for the agency, the same month that Marcum was killed.
Following his eventual arrest and charges, according to Grusing, Kimball would confess to killing at least 21 people and told his attorneys he was responsible for as many as 50 murders.
Authorities would also learn that Scott had killed another stripper, LeAnn Emry, prior to Marcum.
He would also confess to killing woman Kayci Mcloed, who had also gone missing. He had also killed his uncle, Terry Kimball, in 2004.
The FBI was able to build a case against Kimball while he was already in prison and after getting pressure from the families of the women who had disappeared and had last been seen with Kimball, according to Grusing.
The former FBI agent added: “And that's when two dads came to the FBI office to talk to my boss and say, not only was Scott responsible for Jennifer's disappearance, but another girl named Kayci was last with Scott, and that reporting was in the case file.
“But Scott had mastered such that, again, he enjoyed the game, and it was like leaving little breadcrumbs to say, 'I'm so good at this, I can tell you about these homicides, and you'll never know I'm doing them.”
Authorities were eventually able to find McLeod and Emry’s remains. However, Marcum’s remains have never been found.
