Capital punishment in Colorado
Capital punishment is legal in the U.S. state of Colorado.
The death penalty was reinstated in Colorado on January 1, 1975. The previous death penalty statute was declared unconstitutional due to the  or mentally disabled are constitutionally precluded from being executed.
Kennedy v. Louisiana invalidated existing state statutes which made the following crimes punishable by death:
Sentencing and death row
- Nathan Dunlap, convicted and sentenced to death for murdering four people at a Chuck E. Cheese's restaurant in 1994.
- Sir Mario Owens, who was convicted and received a jury's death determination in 2008 for the murder of a young couple, Javad Marshall-Fields and his fiancée, Vivian Wolfe, both prosecution witnesses in a murder trial involving Owens.
- Robert Ray, who ordered the murders of Marshall-Fields and Wolfe while awaiting his own trial for murder.
Until 2011, death row was located in Cañon City, Colorado. That year, the ACLU raised an appeal about human conditions and all three were moved for more access to sunlight. All the murders listed above occurred in Aurora. Prosecutors had sought the death penalty against James Eagan Holmes, perpetrator of the 2012 Aurora shooting.
On January 7, 2011, Colorado Governor Bill Ritter granted a full and unconditional posthumous pardon to Joe Arridy, who had been convicted and executed as an accomplice to a murder that occurred in 1936. The pardon came 72 years after Arridy’s execution and was the first such pardon in Colorado history. A press release from the governor's office stated, "[A]n overwhelming body of evidence indicates the 23-year-old Arridy was innocent, including false and coerced confessions, the likelihood that Arridy was not in Pueblo at the time of the killing, and an admission of guilt by someone else." The governor also pointed to Arridy's intellectual disabilities. He had an IQ of 46 and functioned like a toddler. The governor said, "Granting a posthumous pardon is an extraordinary remedy. But the tragic conviction of Mr. Arridy and his subsequent execution on Jan. 6, 1939, merit such relief based on the great likelihood that Mr. Arridy was, in fact, innocent of the crime for which he was executed, and his severe mental disability at the time of his trial and execution. Pardoning Mr. Arridy cannot undo this tragic event in Colorado history. It is in the interests of justice and simple decency, however, to restore his good name."
On May 22, 2013, Colorado Gov. John Hickenlooper said it was unlikely he would ever allow the execution of convicted killer Nathan Dunlap. Hickenlooper granted Dunlap an indefinite reprieve, citing doubts about the fairness of Colorado’s death penalty.

Current attempts at abolition
In 2009 a bill was introduced that would have abolished the death penalty as an option in criminal cases. It successfully made it through the Colorado House of Representatives, but was halted in the state Senate when it failed to pass a vote that was held there. Besides ending the death penalty in the state of Colorado, the bill planned to use the funds normally dedicated to such trials and use them instead to help fund the Colorado Bureau of Investigation. This department focuses on solving cold cases. The funds would allow for additional staff members. 
Colorado was one of the first states to repudiate the death penalty by abolishing it in 1897 only to restore it once more in 1901 due to a number of lynchings that had occurred. In total, 101 people were executed in Colorado in the pre-Furman period (1859–1967). Eleven of these executions were prior to Statehood; 90 since. All were executed as punishment for murder and all were male.
Colorado is notable for being the last state to make use of lethal gas prior to the 1972 Supreme Court decision that effectively abolished capital punishment in the United States. Colorado performed the last pre-Furman gassing in 1967. Oklahoma performed the last pre-Furman electrocution in 1966. Kansas performed the last pre-Furman hanging in 1965. Utah performed the last pre-Furman execution of a death sentence by firing squad in 1960 (and coincidentally, the first post-Furman execution by firing squad in 1977).
