Jibril Abubakar was 22 and an aspiring medical student from Antioch, California when he was shot and killed on March 23, 2017. He had graduated early from UC Riverside with a bachelor’s degree in political science and was taking chemistry and biology courses at Los Medanos College while preparing for medical school exams; his family says he aimed for a doctoral degree in pharmacy, inspired by his mother’s work as a registered nurse.

The shooting happened in the 2700 block of Contra Loma Boulevard. Another man, 23, was wounded and listed in stable condition. Police initially did not identify a suspect or say whether the two men shot each other or were shot by someone else. Investigators later arrested a 13-year-old who was charged with Jibril’s murder. Jibril’s parents, Patience and Abdul Abubakar, and his sister, Fatima, remember him as kind and selfless.

What details about that night or the motive are still missing to the community’s understanding of what happened?
