After the hearing, members of both families embraced each other and offered sympathies.
Lawson said she believed the justice system worked.
"It has been a very, very tough year," she said. "But now we're very, very satisfied."
Lawson said, "He was the baby of our family, and he was the man of our family."
During the hearing, she said, "There's not enough time to tell you what it's like to lose your 21-year-old baby boy. The hardest part is getting up every morning and knowing he's not here. He's not coming home."
Two of Cordle's sisters also spoke at Burdette's sentencing.
One of them, Danielle Cordle, said she was close to her brother. She said he gave her away at her wedding and was at the hospital for the birth of her children.
"I miss my friend dearly," Cordle said. "You really can't dim a light that was that bright."
Her brother was an organ donor, she said. Two people who were blind are now able to see because of his donated corneas.
The plea agreement was binding, meaning the judge is bound to the sentence agreed upon by the parties. So the sentence Monday was expected.
His attorney told the judge, "Mr. Burdette is here today soul searching over the rest of his life and what he's going to do with it. I can only hope he'll use that time to get an education and some skills that will lead him away from the life that brought him here."
King said to Burdette, "It's a tragic situation all way around. I would remind him and you that the victim in this case will not get any more education and will not enjoy any other aspect of life.
"Mr. Burdette has taken everything he had and ever will have," the judge said.
