“My son was a good boy. He had two parents at home. He had no problems. He went to school. He worked for Bernal Heights Recreation Center. He was working,” Brown said last year. “All he did was one day was walk out the house and see perpetrators getting ready to shoot someone and — because he opened his mouth and said ‘Run!’ — they shot my son with a semi-automatic gun. 30 rounds of bullets.”

The reward for information in Abrakasa’s case stands at $250,000.
