Alabama schedules fourth nitrogen gas execution amid debate over method

Alabama has scheduled its fourth execution by nitrogen gas. Alabama Gov. Kay Ivey on Tuesday set a Feb. 6 execution date for Demetrius Frazier. Her office said the execution will be carried out by nitrogen gas. Frazier was convicted of killing Pauline Brown while burglarizing her Birmingham apartment in 1991. Prosecutors said Frazier, while in police custody in Detroit on an unrelated charged, confessed to raping and shooting Brown. Alabama last year became the first state to carry out an execution with nitrogen gas. Three inmates were put to death using the new method.
