Alabama Executes Convicted Killer Using Controversial Nitrogen Gas Method

Carey Dale Grayson, convicted of a 1994 hitchhiker's murder, became the third person executed by nitrogen hypoxia in the U.S., raising ethical and legal concerns.

Carey Dale Grayson, 50, was executed by nitrogen gas at an Alabama prison for his role in the brutal 1994 murder of hitchhiker Vickie DeBlieux.
This marks the third execution using nitrogen hypoxia in the U.S., a method criticized internationally for its potential to cause suffering and its lack of testing.
Grayson, who chose nitrogen gas over lethal injection, reportedly exhibited visible distress, including gasping and shaking, before being pronounced dead at 6:33 p.m.
The victim's daughter, while condemning Grayson's actions, expressed opposition to the execution, calling for an end to capital punishment under the guise of justice.
The U.S. Supreme Court denied Grayson's last-minute appeal, which argued the method amounted to cruel and unusual punishment due to its unproven nature.
