Colorado Capital Punishment Laws

Capital punishment, also known as "the death penalty," remains a legal sentence under Colorado laws for certain crimes. Colorado has executed a total of 101 people in its history (all of them male and for the offense of murder). However, since the Supreme Court reinstated the death penalty in 1978, the state has only executed one person in 1997 and is considered a "de facto" non-capital punishment state.

That being said, Colorado jurors still have the ability to impose the death penalty. However, the number of cases in which it can be used is limited as it only applies to class 1 felony cases involving certain murders, kidnapping, or treason. Generally, prosecutors must be able to establish at least one aggravating factor in order for the death penalty to apply. These factors can apply to murders which involve:

  • The death of a peace officer, firefighter, emergency services provider, judge, elected official, or federal law enforcement agent;
  • The death of a child under 12;
  • Dynamite or other explosive devices;
  • Pecuniary gain;
  • Especially heinous, cruel or depraved conduct; or
  • Extreme indifference to human life.
