Officers from the Southern District responded around 1:31 AM to the 100 block of 6th Street, where they found a victim suffering from gunshot wounds, according to the San Francisco Police Department. The victim was taken to a local hospital and later died. Investigators identified 33-year-old Siaosi Aleamotua as the suspect and took him into custody later that morning on a murder charge.
