Abrakasa was just 17-years-old when he was gunned down at the corner of Grove and Baker streets in San Francisco, exactly seven years ago.
"His life was cut short that day. And that day my life changed. It's never been the same," said Paulette Brown, Abrakasa's mother.
Brown is marking the anniversary by returning to the place where her son was shot 30 times. She's posting signs and passing out flyers about the unsolved crime.
"Who's to say that they won't do it again?" said Brown.
Abrakasa played basketball at Raoul Wallenburg High School and was about to start his senior year. Many believe witnesses are out there, but too frightened to come forward.
"My experience, and I work in the criminal justice system, usually went something like this happens, it's on Facebook and everybody knows who done it, but because who's going to protect you if you come forward to tell?" said George Jurard, Brown's husband.
For years, Brown fought publicly for a reward in her son's case. Then-Mayor Gavin Newsome established $250,000, but so far no takers. Police say initially suspects were arrested in Aubrey's murder, but released due to lack of evidence. They need witnesses to come forward.
Brown: "That building there, you can clearly see, you can clearly see."
Barnard: "You think someone saw something from there?"
Brown: "Oh yes."
She was joined by other mothers whose son's killings are also unsolved. She calls them her healing circle.
"This is my therapy and I'd rather do this and maybe, maybe one day I'll get justice," said Brown.
Brown says she won't stop until she does.
