Lucas was executed on April 27, also in Georgia.
The 37-year-old requested a stay of execution which was not granted. He was given lethal injection shortly before 10pm local time for the deaths of three people.
Lucas was convicted on the April 1998 murders of Steven Moss and his two children, Bryan, 11, and Kristin, 15.
The Georgia man was inside the Moss home when the trio returned from school. He shot and killed all three family members.
For his last meal, he ate pizza, steak and a cheese calzone, as well as a stuffed portobello mushroom, a salad and orange juice. He apologised to the victims’ families with his last words.
“I would like to say I’m sorry to Mrs Moss and the family,” he said.
