JACKSON — A 38-year-old inmate who was convicted of killing two college students after confessing to his FBI agent father was executed in Georgia on Thursday, apologizing to the families of both victims before being injected at a state prison.
Andrew Allen Cook was pronounced dead at 11:22 p.m., about 14 minutes after he was injected with the sedative pentobarbital. He was the first inmate to be executed since the state changed its procedure in July from a three-drug combination to a single dose.
With his last words, he apologized to the families of Mercer University students Grant Patrick Hendrickson, 22, and Michele Lee Cartagena, 19, who were shot several times as they sat in a car at Lake Juliette, which is about 75 miles south of Atlanta. He said what he did was senseless.
"I'm sorry," Cook said as he was strapped to a gurney. "I'm not going to ask you to forgive me. I can't even do it myself."
He also thanked his family for "their support, for being with me and I'm sorry I took so much from you all."
The Georgia Appeals Court on Wednesday temporarily stayed Cook's execution to consider a challenge to the state's lethal injection procedure. But the Georgia Supreme Court lifted the stay Thursday and all other appeals were exhausted.
Cook's lawyers have argued at various stages in their appeals of his death sentence that he suffered from mental illness and was being treated for depression up to the time of his death.
Mary Hendrickson, the mother of one of the victims, recently told television station WMAZ-TV in Macon she's been waiting 18 years for justice.
"I think that's what it was: the devil's work," she said. "When all that is going on, I was just thinking to myself: 'Well, the devil is not going to win. He's not going to win over my heart. He is not going to win.'"
