A District man was sentenced to 48 years in prison Friday for walking into a barbershop during the middle of the day and brazenly shooting a man sitting in a barber chair getting a haircut.

In December, a D.C. Superior Court jury found Antwon D. Green, 29, guilty of felony first-degree murder while armed in the 2014 fatal shooting of Breond Keys, 38.

According to prosecutors, Green ran into the Kutt-N-Up shop in the 1400 block of Good Hope Road SE at 11 a.m. Dec. 10 in 2014 and shot Keys multiple times as Keys’s barber and others in the shop ran to hide.

Before fleeing, prosecutors say, Green rummaged through Keys’s pockets as Keys lay on the floor dying. Authorities found Green’s DNA on Keys’s pocket as well as on a bullet shell casing inside the barbershop.

At his sentencing in D.C. Superior Court, Green told Judge Judith Bartnoff that he was innocent.

“Unfortunately, I am here because of someone else’s death. The evidence against me in this case doesn’t explain what really happened to Mr. Keys,” Green said before he was sentenced.

“Nobody in this courtroom is a saint. I am definitely not the best person. But I am a likable person. I like guns. But I don’t like what guns do to people. But if I have to protect myself, I will,” he said.

As part of his sentence, Green will have to serve at least 30 years before he becomes eligible for early release. Green will begin serving his prison term after he completes his current six-year prison sentence for an armed robbery that occurred just weeks after Keys’s murder.
