Scott Lee Kimball Admits To Four Colorado Murders In Letter

Scott Lee Kimball, the former FBI informant who pleaded guilty to two counts of second-degree murder in October, 2009 has finally admitted to the murders of 4 Colorado residents.

Kimball, who was already serving a lengthy prison sentence, pleaded guilty to the murders despite claiming that he "did not act alone." He claimed to be "part of a very intricate state, regional and international organized-crime enterprise that involved millions of dollars."

However, Kimball recently took responsibility for the crimes in a letter to his family, a summary of which was obtained by the Boulder Daily Camera.

The Camera reported that Kimball took full responsibility for the killing of Kaysi McLeod, 60, of Westminster and LeAnn Emry, 24, of Centennial, Jennifer Marcum, 25, of Aurora, and Terry Kimball, 60.

"This confession is not offered to solicit sympathy, compassion or understanding from any of you. It is HOWEVER about truth and justice," Kimball reportedly wrote near the beginning of the 147-page letter

Kimball is currently serving a 70-year sentence in connection with his 2009 guilty plea.
