Hasan Semaj Humphries was 17 when he was fatally shot on January 13, 2020, in the 1400 block of 48th Avenue in Oakland at about 4:44 p.m. The shooting prompted a major investigation by the Oakland Police Department and deeply affected the community; Hasan’s family started a GoFundMe to help cover funeral costs.

Investigators identified 18-year-old Jacobi Julius Gaines of Union City as the primary suspect. Witness statements and video surveillance were cited in identifying Gaines. A warrant led to his arrest at an Oakland apartment, where officers reported finding clothing matching descriptions from the shooting and a pistol matching the caliber used. Charges filed included murder and multiple firearm offenses, with his felony probation status from a prior conviction noted in filings.
