A man will serve life in prison after pleading guilty to the Thanksgiving Day shooting deaths of his mother and his stepfather, according to the Cobb County District Attorney’s Office.

Dustin Ray Dixon, 38, of Woodstock, was convicted of two counts of malice murder and two counts of aggravated assault Monday in the 2015 double killing at the couple’s Acworth home.

Dixon emerged from the basement of the Camden Lake Drive residence in the Camden Pointe subdivision just before 7 p.m. Nov. 26, according to Cobb District Attorney John Melvin.

“He was angry with his mother and stepfather, and he was armed with a .40-caliber handgun,” he said in a news release.

Dixon shot and killed 60-year-old Ellen DeLoach and 58-year-old Michael “Brad” DeLoach, according to Melvin.

Ellen DeLoach, 60, was a local artist whose paintings had been exhibited at the Bill Lowe Gallery in Atlanta.

“He also fired shots at his grandmother and his aunt, who managed to flee the residence and call Cobb police,” Melvin said. The grandmother and aunt were not harmed in the shooting, AJC.com previously reported.

“Officers located a male suspect in the front yard and detained him without incident,” police spokeswoman Alicia Chilton said after the fatal shooting.

Several psychiatrists concluded that Dixon was not competent to stand trial after periodically evaluating him in the years since his arrest, according to prosecutors.

“But treatment at Georgia Regional Hospital within the last year successfully restored Dixon’s mental competency, according to Dr. Joseph Browning, who testified during the plea hearing,” Melvin said.

The two family members who survived the incident attended Monday’s hearing, according to authorities.

“Some,” Melvin said, “wiped away tears.”
