Charles Frederick Warner, who had originally been scheduled to die April 29, the same day as Lockett, was pronounced dead at 7:28 p.m. CST at the Oklahoma State Penitentiary in McAlester, the news site reports. He was convicted in 2003 of the rape and murder of his then-girlfriend's 11-month-old daughter.
"Justice was served tonight as the state executed Charles Warner for the heinous crime of raping and murdering an infant," Oklahoma Gov. Mary Fallin said, according to CNN.
Even after he was injected, Warner reportedly kept talking. Associated Press reporter Sean Murphy, who was among the witnesses of the death, recalled Warner's words.
"'They poked me five times. It hurt. It feels like acid,' " Warner said, according to Murphy, CNN notes. "'I'm sorry for all the pain that was caused. I'm not a monster. I didn't do everything they said I did. I love people. I love my family. I love Jesus.' "
Once the procedure started, Warner also said, "My body is on fire," CNN reports.
However, according to CNN, despite his statements, there were no outward signs of distress or suffering, Murphy noted.
