Repealing the death penalty in Colorado will be under review with a bill introduced in the state Legislature.
The proposal to abolish capital punishment got introduced in the House on Friday.
There are currently three men on Colorado's death row. But if the bill becomes law it would not apply to current cases, including the man charged in last summer's Aurora theater shootings. Prosecutors are weighing whether to seek the death penalty in that case.
One of the three men on death row, Nathan Dunlap, has exhausted his appeals and an execution date could be set soon. He was convicted in the shooting deaths of four people at an Aurora Chuck E. Cheese in 1993.
The last time Colorado executed someone was 1997.
