Scott Kimball — The Serial Killer from Colorado

Who Is Scott Kimball?

Scott Lee Kimball is an American serial killer who committed at least four murders in the state of Colorado and surrounding areas in the early 2000s. What makes the Kimball case particularly remarkable is not only the brutality of the crimes, but the fact that he operated for a period as a registered FBI informant — a role he allegedly exploited to sidestep suspicion and move freely while investigators searched for the missing victims.

For years, Kimball managed to present himself as a respectable citizen. He was married, ran businesses, and portrayed himself as a well-connected, successful man. Beneath the surface, he systematically manipulated the people closest to him and eliminated anyone he considered a threat to his facade or his interests.

The Victims — Family Members and Acquaintances

The four confirmed victims in the case all had a direct connection to Kimball, either through family ties or personal acquaintance:

- Vickie Montoya — a woman in Kimball's social circle whose disappearance went unsolved for a long time.

- Terry Kimball — Scott's stepfather, who disappeared in 2003. The murder reflects Kimball's willingness to kill even within his immediate family.

- Jennifer Marcum — a young woman with whom Kimball had a relationship. She disappeared in 2003 and was never found alive.

- LeAnn Emry — Kimball's niece, who likewise disappeared and was subsequently confirmed as a victim.

A recurring pattern throughout the case is that Kimball made his victims vanish without leaving a trace. The bodies were buried in remote locations across Colorado and Wyoming, and it took years of investigation — along with Kimball's own confessions — to locate them.

The FBI Informant Who Murdered

One of the most controversial dimensions of the case is Kimball's role as an FBI informant. He was recruited as a source in connection with fraud investigations and used that status to build credibility with authorities. Critics have since asked whether the FBI's collaboration with Kimball inadvertently provided him with protection or room to operate during the period in which the murders took place.

The FBI has denied that the agency had any knowledge of Kimball's criminal activities beyond what was covered by the informant agreement. Nevertheless, the case raises serious questions about the use of criminal informants and the level of oversight authorities exercise over them.

Discovery and Arrest

Suspicion of Kimball grew gradually as people in his circle kept disappearing. It was not until investigators began connecting the separate missing-persons cases that a pattern emerged. Kimball was already in custody on fraud charges when detectives intensified their efforts to link him to the missing individuals.

During interrogations, Kimball eventually disclosed information about where the bodies were located — details he used as bargaining chips. This behavior is characteristic of manipulative perpetrators who seek to retain some form of control even while in custody.

The Trial and Sentence

In 2010, Scott Kimball pleaded guilty to four counts of murder. A Colorado court sentenced him to 70 years in prison, effectively ensuring he would never return to society.

During the sentencing proceedings, prosecutors highlighted not only the individual murders but also the systematic deception Kimball had constructed over many years. He had built an identity as a credible businessman whom no one would suspect of crimes of this nature — a facade that held long enough for four people to lose their lives.

Legacy and Lessons

The Scott Kimball case has since been used as an example in discussions about law enforcement's use of criminal informants, and about how serial killers can conceal themselves behind respectability and social roles. It demonstrates that proximity to power — in this instance, the FBI — is no guarantee of innocence, and that investigators should never allow institutional relationships to stand in the way of rigorous scrutiny of suspects.

For the families of the victims, the verdict has brought a measure of justice, but the grief and the unanswered questions remain. Several of the bodies were never fully recovered, and parts of Kimball's activities during the murder period have still not been entirely pieced together.
