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.
