A doctor started to administer the first drug, a sedative intended to knock the man out and forestall pain, at 6:23 p.m. Ten minutes later, the doctor announced that Mr. Lockett was unconscious, and he started to administer the next two drugs, a paralytic and one intended to make the heart stop.
At that point, witnesses said, things began to go awry. Mr. Lockett’s body twitched, his foot shook and he mumbled, witnesses said.
At 6:37 p.m., he tried to rise and exhaled loudly. At that point, prison officials pulled a curtain in front of the witnesses and the doctor discovered a “vein failure,” Mr. Patton said.
Without effective sedation, the second two drugs are known to cause agonizing suffocation and pain.
Mr. Lockett’s apparent revival and writhing raised questions about the doctor’s initial declaration that he was unconscious and are sure to cast doubt on the effectiveness of the sedative used.
