Security guard Sefanaia Alatini, 37, of Oakland, is accused of shooting the man in the parking lot, located at 105 Turk Street in the Tenderloin neighborhood, just before 9 a.m. on February 11, investigators said. Paramedics performed CPR before the victim was pronounced dead at the scene.<\/p>\n
District Attorney Brooke Jenkins held a news conference to announce that her office charged the guard with murder. Alatini is a convicted felon who is prohibited from possessing firearms, according to the charges.<\/p>\n
Leading up to the deadly shooting, there was a \u201cconfrontation\u201d between the security guard and the victim, Jenkins said. Alatini pulled out a gun, and the victim pulled out pepper spray, according to the DA.<\/p>\n
\u201cThe victim took out pepper spray and sprayed in the direction of the (guard) before walking away,\u201d Jenkins said. The victim did not use his pepper spray until after Alatini brandished a gun, she said.<\/p>\n
The victim had already turned around and was walking away from the confrontation when he was shot, Jenkins said.<\/p>\n
Prosecutors said they will rely heavily on surveillance videos to rebut self-defense claims. \u201cWe have cameras all over the city,\u201d the DA told reporters. \u201cWe do not believe there is significant evidence of self defense in this case.\u201d<\/p>\n
\u201cHe was shot in the back,\u201d she emphasized. <\/p>\n

Jenkins said the victim was not a customer who used the parking lot. <\/p>\n
Murder charges were also filed this week for a second, unrelated case stemming from a \u201cvery violent robbery\u201d on February 5, the district attorney told reporters. The victim was assaulted and gravely injured in the area of Bush Street and Taylor Street, according to the San Francisco Police Department.<\/p>\n
Officers found the victim lying alone on the street, and there were no witnesses around who saw what happened to him, Jenkins said. He was \u201csuffering from significant\u00a0skull fractures and internal bleeding,\u201d she said. <\/p>\n
Surveillance videos later revealed that he was beaten by a man wielding a 2-by-4 wooden board, and the killer stole his backpack before fleeing the scene. <\/p>\n
\u201cHours after the assault, Mr. Vivero was captured on surveillance camera in the Tenderloin and Union Square areas allegedly wearing the same clothing and the victim\u2019s backpack,\u201d prosecutors wrote. <\/p>\n
