Four Men Plead Guilty in Bayview Drive-By Shooting Case

Four men have pleaded guilty in connection with a September 2023 drive-by shooting in San Francisco’s Bayview District that injured one person and drew a multi-agency federal investigation spanning the broader Bay Area.

The San Francisco District Attorney’s Office announced Monday that all four defendants have now entered guilty pleas. Two of them, Shaquille Dumetz, 32, and Cory Martin-Turner, 31, were sentenced back in December. Dumetz pleaded guilty to attempted murder and received a seven-year sentence. Martin-Turner pleaded guilty to assault with a semiautomatic weapon and received six years.

The remaining two defendants, Phillip Stewart, 33, and Jahari Oliver, 28, each pleaded guilty to assault with a semiautomatic weapon this week and face sentencing at a hearing Wednesday. Both are expected to receive six-year sentences.

According to prosecutors, the four men left a residence in Oakland together on September 7, 2023, and drove to San Francisco in two vehicles. Martin-Turner drove a Hyundai. Stewart drove an Infiniti G37. Roughly an hour after leaving Oakland, the group fired into a home on Donner Avenue while targeting a victim who was standing outside talking to someone in a parked car. The victim was struck in the thigh. No one else was hurt.

The investigation that followed stretched well beyond the San Francisco Police Department. The FBI, ATF, and Oakland police all contributed to the case, and in February 2024 investigators executed search warrants at seven locations across the Bay Area. Those searches turned up multiple illegal firearms, including eight handguns and a rifle.

District Attorney Brooke Jenkins addressed the case directly in a statement. “These convictions and sentences hold these men accountable for a brazen mid-afternoon drive-by shooting,” Jenkins said. “Although I am grateful no lives were lost in this incident, it should be clear to them that gun violence will never be normalized nor tolerated in San Francisco. Anyone with the intention of coming to San Francisco to engage in violence, with the belief that they will get off with no consequences, is mistaken.”

Jenkins also pointed to a pattern her office has been tracking: criminal networks that operate across city and county lines. “We have seen an uptick in the regional nature of these particular types of crimes,” she said, connecting that trend to displacement driven by housing costs and gentrification. Her argument is that longtime San Francisco residents who have been priced out into other parts of the Bay Area sometimes maintain criminal ties to the city.

That framing is worth examining carefully. Jenkins is weaving together two threads, regional crime coordination and housing displacement, that don’t always move together. The claim that gentrification is a contributing driver of cross-jurisdictional violence is a sociological argument, not a prosecutorial finding, and it deserves more scrutiny than a press release typically invites. Still, the underlying observation that Bay Area gun violence increasingly requires multi-jurisdictional responses reflects what law enforcement has been saying for several years.

What the case does demonstrate clearly is that the investigation worked. Four men drove from Oakland into a residential neighborhood in Bayview, fired into a home in the middle of the afternoon, injured a person, and then drove home. Three years later, all four are heading to state prison. The federal cooperation, the search warrants, the eventual seizure of illegal weapons: that is how these cases are supposed to go, and they don’t always go that way.

Bayview has historically carried a disproportionate share of San Francisco’s gun violence, and residents there have pushed for years to see cases like this prosecuted through to conviction rather than dropped or pled down to minimal consequences. Wednesday’s sentencing hearing will close the last chapter on this particular shooting.

For anyone keeping score on the DA’s office under Jenkins, this is a clean win: four defendants, four guilty pleas, sentences ranging from six to seven years, and a pile of illegal guns pulled off the street in the process. The harder question, which no conviction alone can answer, is whether those sentences deter the next group that makes a similar drive across the Bay.
