San Francisco prosecutors file murder charges in Nob Hill robbery beating and Tenderloin security-guard shooting case

Two killings, two suspects, and a common thread of surveillance evidence

San Francisco prosecutors have filed murder charges in two separate homicide investigations stemming from incidents that occurred this month in the Nob Hill and Tenderloin neighborhoods. The cases involve different alleged circumstances—one an assault and robbery, the other a shooting during an altercation—but both rely heavily on surveillance video and police investigative work to identify suspects and support charging decisions.

Nob Hill case: robbery and a fatal head injury

In the Nob Hill matter, prosecutors charged 34-year-old Eduardo Vivero with murder and second-degree robbery in connection with a Feb. 5 attack near Bush and Taylor streets. Court records describe an assault in which the victim was struck in the head with a wooden board and fell to the ground. The assailant then fled with the victim’s bag.

The victim was hospitalized with life-threatening injuries and later died on Feb. 21. Court records describe the injuries as including a severe skull fracture and internal bleeding. Investigators also documented the recovery of a broken 2x4 wooden board in the area.

Police arrested Vivero on Feb. 19 after locating him in the Tenderloin, where officers reported seeing him holding drug paraphernalia. He was booked into San Francisco County Jail. Authorities have also referenced an outstanding warrant from San Mateo County in connection with his booking history.

Tenderloin case: fatal shooting and a disputed self-defense account

In the second case, prosecutors charged 37-year-old Sefanaia Alatini, an Oakland resident, with murder and firearms-related offenses after a Feb. 11 shooting on the 100 block of Turk Street. Police said officers responded at about 8:55 a.m., found an adult male suffering from a gunshot wound, and attempted lifesaving measures. The victim was declared dead at the scene.

Authorities said Alatini was detained during the investigation and later arrested on probable cause. Police booked him for murder as well as being a felon in possession of a firearm and a felon in possession of ammunition.

Prosecutors have described Alatini as working as a parking lot security guard and have outlined a contested sequence of events. Alatini claimed he was pepper-sprayed before he fired. Prosecutors, however, pointed to surveillance video that they say shows him brandishing a gun before the victim was shot as the victim attempted to retreat. Prosecutors said the evidence, as presented in court filings, does not strongly support a claim of self-defense.

What happens next in court

Filing a murder charge initiates felony proceedings that typically move through arraignment and subsequent hearings in San Francisco Superior Court. In both cases, the defendants are presumed innocent unless and until proven guilty beyond a reasonable doubt.

• Feb. 5, 2026: Alleged Nob Hill assault and robbery near Bush and Taylor
• Feb. 11, 2026: Tenderloin shooting on Turk Street; victim pronounced dead at scene
• Feb. 19, 2026: Arrest of Eduardo Vivero
• Feb. 21, 2026: Death of the Nob Hill victim

Both investigations highlight the growing role that video evidence—from nearby cameras and surrounding businesses—can play in rapidly identifying suspects and testing competing accounts of what happened.

The two cases will proceed independently through the criminal court process, with prosecutors expected to continue disclosing evidence and defense attorneys expected to challenge the allegations and the interpretation of video and witness accounts.
