Scott Lee Kimball

Scott Lee Kimball (born September 21, 1966) is a convicted serial killer from Boulder County, Colorado. He is serving a 70-year sentence after pleading guilty in 2009 to the murders of Kaysi McLeod, 19; Jennifer Marcum, 25; LeAnn Emry, 24; and Kimball's uncle, Terry Kimball, 60.All four victims died between January 2003 and August 2004, while Kimball was on "supervised release" after a prior check fraud conviction, serving as an FBI informant. Marcum remains missing and is presumed dead, while the other three bodies were recovered in remote Colorado and Utah locations.

Kimball has boasted to friends of multiple other murders, but authorities have uncovered no direct evidence corroborating his claims.

Kimball was born in Boulder, Colorado. He was convicted of check fraud after stealing over $50,000 from an optometrist who shared an office with his mother, an insurance agent. Kimball was sentenced to prison for fraud, but was released in 2003.

His early release came after he convinced FBI agents that he would work for them as an informant. In prison, Kimball had befriended fellow convict Steve Ennis who was allegedly plotting to kill his estranged girlfriend Jennifer Marcum. Given that Marcum was expected to testify in an important trial about a methamphetamine distribution ring, FBI agents agreed to work with Kimball. Kimball went on to kill Marcum and three others.

Kimball is currently serving his sentence at Colorado State Penitentiary.

In September 2010, it was reported that the FBI was investigating Kimball as a possible suspect in the murder and mutilation of a woman found in Westminster, Colorado, in October 2004, while Kimball lived in the area under FBI supervision.

In December 2010, Kimball told a cousin that he had been proposed as a suspect in the West Mesa murders in New Mexico, which were committed during the same 2003-2005 time period.He denied involvement.

The CBS News series 48 Hours outlines Kimball's case in an episode titled "Hannibal Unmasked", originally aired April 2010.

The NBC News series Dateline NBC aired another telling of the Kimball story on September 21, 2018, with updates since the CBS version.
