Alabama is set to execute Demetrius Terrence Frazier on Thursday using nitrogen gas, making it the nation’s fourth execution by this method. Frazier, 52, was convicted of murdering Pauline Brown after breaking into her Birmingham apartment in 1991.
He also confessed to killing a 14-year-old girl in Michigan, where he was previously serving a life sentence.
Frazier’s family and anti-death penalty advocates pleaded with Michigan’s governor to intervene, but the state declined to take him back.
Critics of nitrogen gas executions argue the method may cause distress, though a federal judge upheld its use.
