The single-drug injection began at about 11:08 p.m. Cook blinked his eyes a few times, and his eyes soon got heavy. His chest was heaving for about two or three minutes as his eyes closed. Not too long after, two doctors examined him and nodded and Carl Humphrey, warden of the state prison in Jackson, who announced the time of death.
Corrections officials said Thursday evening that Cook had received visits from family earlier in the day and ate the last meal he had requested — steak, a baked potato, potato wedges, fried shrimp, lemon meringue pie and soda.
A jury sentenced Cook to death after he was convicted in the January 2, 1995 slayings at Lake Juliette. Cook wasn't charged until more than two years later. He confessed to his father, a Macon FBI agent who ended up testifying at his son's trial.
The Georgia Bureau of Investigation reached out to John Cook in December 1995 because they were interested in speaking to his son. When he called his then-22-year-old son to tell him the GBI wanted to talk to him, he had no idea the younger man was considered a suspect.
"I said, 'Andy, the GBI is looking for you concerning the Lake Juliette homicide. Do you know anything about it?'" John Cook testified at his son's trial in March 1998. "He said, 'Daddy, I can't tell you. You're one of them. ... You're a cop.'"
Eventually, Andrew Cook told his father that he knew about the slayings, that he was there and that he knew who shot the couple, John Cook recalled.
"I just felt like the world was crashing in on me. But I felt maybe he was there and just saw what happened," he said. "I then asked, 'Did you shoot them?'
