OAKLAND — Authorities on Tuesday released a sketch of a person involved in the shooting of a man last August in Oakland.

The shooting happened shortly after midnight on August 30 in the 500 block of East 18th Street. When officers arrived, they found two men, ages 20 and 18, suffering from gunshot wounds.

The 20-year-old man, identified as Demani William, was pronounced dead at the scene.

The 18-year-old man was taken to hospital but survived.

In addition to releasing a sketch of a person of interest, authorities said the suspect was driving a white Ford F-150.

Oakland police have not released a motive for the fatal shooting. When authorities first identified the victim in October, police were investigating the possibility that he had something to do with a gang.

A loaded handgun with an extended magazine was found in the victim’s vehicle, police said.

In the days following William’s death, his Instagram page was flooded with condolences. There were also several comments from a report that mocked his violent death, including one that suggested he had first-hand knowledge of where he was shot.

Anyone with information about the case can contact the OPD Homicide Division at 510-238-3821 or the hotline at 510-238-7950.
