NBC’s “Dateline” on Friday will air a special about Scott Kimball, the Boulder County serial killer who murdered at least four people while working as an informant for the FBI in the early 2000s.

The two-hour episode, titled “A Deal with the Devil,” will air at 9 p.m. Friday on NBC, according to a release from “Dateline.”

“Keith Morrison reports on a notorious serial killer, nicknamed Hannibal, who murdered several people while working as a confidential informant for the FBI,” “Dateline” NBC said in the release. “The two-hour broadcast tells the inside story of how he was ultimately caught.”

The show will include an interview with Gary Thatcher, a Boulder District Attorney’s Office investigator who at the time was a Lafayette police detective and the lead investigator on the Kimball case.

The show also will interview several FBI personnel and Lori McLeod, the mother of one of Kimball’s victims.

Kimball admitted in a 147-page letter to being responsible for the deaths of Kaysi McLeod, 19; Jennifer Marcum, 25; LeAnn Emry, 24; and his uncle, Terry Kimball, 60.

The bodies of McLeod, Emry and Terry Kimball were all recovered in Colorado and Utah, while Marcum was never found but is presumed dead.

Kimball pleaded guilty in 2009 to two counts of second-degree murder and was sentenced to 70 years in prison. He is housed at Sterling Correctional Facility, and is not eligible for parole until 2054.
