Between 1990 and 2021, for adult offenders, Colorado punished felony murder with a mandatory minimum sentence of life without parole. Felony murder was classified as a class 1 felony, along with other theories of first-degree murder, such as after-deliberation and extreme indifference murder, as well as first-degree kidnapping, until Governor Jared Polis signed Senate Bill 124, effective September 15, 2021, reclassifying the offense to a class 2 felony. As a result, felony murder is now punishable by a sentence of 16-48 years.

The purpose of this study is to provide a statistical portrait of people who have been convicted of felony murder between 1990 and 2021. Data were acquired through open records requests from the Colorado Department of Corrections (“CDOC”) and the State Court Administrator’s Office (“SCAO”), along with public data from the Colorado State Demography Office. This study’s primary unit of analysis is a criminal case, meaning a criminal case identifiable by a single case number in which a person was found guilty. With respect to felony murder, a felony murder case means one with one or more felony murder convictions where no other theory of first-degree murder was proven with respect to that or those homicide(s).
