An FBI Informant at the Center of Four Murders
Scott Lee Kimball was a Colorado career criminal who became a paid FBI informant and later admitted responsibility for the deaths of Jennifer Marcum, Kaysi McLeod, LeAnn Emry, and Terry Kimball.
In 2009, Kimball pleaded guilty in Boulder County to two counts of second-degree murder under a plea structure that covered responsibility for all four killings. He received a 70-year sentence.
The Victims
- Jennifer Marcum — remains have not been recovered.
- Kaysi McLeod — remains were recovered in northwest Colorado.
- LeAnn Emry — remains were recovered in southeastern Utah.
- Terry Kimball — Scott Kimball’s uncle; remains were recovered near Vail Pass.
The Informant Problem
Kimball’s case became especially disturbing because he was working as a federal informant while some of the murders occurred. The case raised serious questions about informant management, supervision, and whether his relationship with law enforcement gave him additional freedom to manipulate people around him.
From Fraud Investigation to Murder Case
Kimball had a long history of fraud and forgery. The investigation that eventually exposed the murders grew out of other criminal conduct and a widening examination of the people who had disappeared around him.
Confirmed Versus Suspected
| Category | Status |
|---|---|
| 4 known victims | Kimball accepted responsibility for these deaths in the 2009 plea resolution. |
| Additional suspected victims | Investigators have examined Kimball in relation to other unsolved cases, but suspicion is not conviction. |
| Jennifer Marcum | Still missing; her remains have not been found. |
What Authorities Knew — And When
2003–2004
The four known victims disappear or are killed while Kimball is operating in Colorado and neighboring states.
2006 onward
Investigators increasingly focus on Kimball through fraud cases, missing-person links, forensic work, and interviews.
2008–2009
Victims’ remains are recovered in Colorado and Utah as investigators build the homicide case.
October 2009
Kimball pleads guilty in Boulder County and is sentenced to 70 years.
Jaded Evidence: Why This Case Matters
Kimball’s case is not only about four murders. It is also about the vulnerabilities created when a sophisticated manipulator is granted credibility and freedom because he is useful to law enforcement.
Informants are investigative tools. They are not proof of reliability.
