David Homer Edenfield was born on June 4, 1948. He grew up in the United States.

On March 8, 2007, Christopher Barrios Jr. was lured to the mobile home of the Edenfield family in Brunswick, Georgia. Once there, he was assaulted by George Edenfield and David Edenfield. They strangled him after he threatened to tell his family about the abuse. Peggy Edenfield, George's mother, was present during the attack and engaged in inappropriate behavior.

After the murder, David Edenfield admitted that the three family members continued to engage in sexual acts before calling a friend to help them dispose of Christopher's body. A week later, on March 15, 2007, a state ranger discovered Christopher's body hidden in black plastic garbage bags in a wooded area near his home.

The police arrested George, David, and Peggy Edenfield, accusing them of kidnapping and murdering Christopher. They also arrested Donald Dale, who was charged with helping conceal the body but later pleaded guilty to lying to the police. In the trial, Peggy Edenfield testified against both David and her son George. For her cooperation, she avoided the death penalty and received a sentence of sixty years in prison.

David Edenfield's murder trial began on September 29, 2009. The prosecution used his videotaped confession and testimony from his wife. Medical examiner Dr. Jamie Downs also testified about the trauma on Christopher’s body, which matched David's confession. After only two hours of deliberation, the jury found David guilty on all counts on October 5, 2009. The following day, he was sentenced to death.

As of June 2023, David Edenfield remains on death row, awaiting execution. George Edenfield was found to be mentally incompetent to stand trial and was sent to a state mental hospital for evaluation. David Edenfield had a history of prior assaults, including a conviction for incest with his daughter in 1994, for which he received ten years of probation.
