Charles Warner, who was executed Thursday for the killing of an 11-month-old girl in 1997, said during his last words: “It feels like acid.” The comment came before any of the lethal drugs were administered and while he was only receiving a saline drip through an intravenous line.

While on the gurney, he also said he’d been “poked” five times.

Warner’s attorney who witnessed his execution, Madeline Cohen, said since she wasn’t able to view the IV insertion, she asked Warner to tell her how many times the execution team tried to insert the line and whether he was experiencing any problems.

Cohen said she and Warner’s family members found Warner’s comments “disturbing” and “confusing.”
