Derrick Williams, 23, was killed on January 1, 2015, at a Valero gas station at 7225 Bancroft Avenue in Oakland. Poole allegedly grabbed a gold chain from Williams and, during the struggle, fatally shot him. Williams was pronounced dead at the scene.

Investigators used surveillance footage from the gas station to document the moments before the shooting. The case led to charges against three people: Andre Poole was charged with first-degree murder with a special circumstance for committing murder during a robbery; Marcus Mayfield faced second-degree murder and attempted voluntary manslaughter counts; and Dwight Hilton initially had murder charges dismissed but later pleaded no contest to second-degree robbery in an unrelated case. The account reports Poole was convicted and faces life without parole, and Mayfield received a plea resulting in 20 years to life; Hilton is serving seven years.

Are there witnesses who remember the activity at that gas station that night or who can provide more detail about the people involved?
