A Clayton County jury took less than two hours to convict a man of double murder in the case of a 2011 drug deal gone bad.

Christopher Antwon Bradshaw, 28, was sentenced to two consecutive life prison terms for fatally shooting teens Devonta Emon Stembridge and Dion Leonard Brice.

“This killing for drugs and money has got to stop,” Clayton County Superior Court Judge Deborah Benefield told Bradshaw as she handed down the sentence.

Bradshaw was found guilty of all charges levied against him, including double counts of murder, aggravated assault, felony murder – committing a felony that causes another’s death – and evidence tampering.

Police found the bodies of Stembridge, 19, and Brice, 16, inside a car parked in College Park on June 25, 2011, after they allegedly trying to sell Bradshaw some fake marijuana, according to reports.

Investigators were able to quickly retrace clues back to Bradshaw and Michael Boykin Jr., who was 18 at the time.

Boykin, who faces the same charges as Bradshaw, testified during the trial that Bradshaw was the sole shooter.

Phyliss Stembridge, the mother of Devonta Stembridge, called Bradshaw “cold-hearted” during the victim impact statement that preceded sentencing.

“He had no remorse,” Stembridge said. “He had the nerve to stare me in the face. He’s a killer. He’s a cold-hearted killer.”

A date for Boykin’s trial has yet to be determined.
