Alabama man set for execution using nitrogen gas in 1994 hitchhiker murder case

An Alabama prisoner, Carey Dale Grayson, is set to be executed on Thursday for the 1994 murder of hitchhiker Vickie Deblieux. He will be the third person executed using nitrogen gas, a new method introduced this year. Grayson, 50, was convicted alongside three teenagers, but he is the only one facing a death sentence as the others were under 18 at the time. His execution has faced legal challenges regarding the new method's constitutionality and its effectiveness. Critics argue that the first two nitrogen executions showed signs of distress, raising concerns about the method. Alabama officials maintain that the protocol is constitutional and has been effective in previous cases.
