Stephen Barbee, 55, received a lethal injection at the state penitentiary in Huntsville. Barbee received a lethal injection on the same day that Arizona executed Murray Hooper for killing two people during a home robbery in Phoenix on New Year’s Eve 1980. Hooper received a lethal injection Wednesday morning. So far, 15 people, including Barbee, have been executed across the US in 2022, all by lethal injection. Barbee’s spiritual adviser held his right hand and prayed aloud while the lethal injection was administered.
