The fatal shooting of an unarmed black man by sheriff's deputies in the South Los Angeles-area neighborhood of Willowbrook last week has led to the threat of a lawsuit and outrage on social media — including emotional pleas from an L.A. rapper to the city's mayor.Ryan Twyman, a father of three, was shot dead in the parking lot of an apartment complex at San Pedro and 132nd streets on the evening of June 6. Deputies had approached a car Twyman was inside just before firing shots, according to the Los Angeles County Sheriff's Department.The 24-year-old was pronounced dead at the scene. He was still inside a vehicle when he died of multiple gunshot wounds, according to corner's officials.Speculation about the number of times Twyman was shot has surfaced in dozens of social media posts in the days since. But the Sheriff's Department has released few details — no information about how many times he was shot and no description of any crime he may have been suspected of.The department has, however, confirmed that no weapon was found at the scene.A brief statement emailed by department spokesman Hamilton B. Underwood expresses condolences to Twyman's family and states the Los Angeles County District Attorney's Office is expected to investigate.But many questions remain unanswered as the Los Angeles County Department of Medical Examiner-Coroner has still not released its findings.Meanwhile, multiple witnesses have recalled seeing two deputies approach the parked car before shooting several times."The police opened the door, and said he had a gun and just started shooting. Never asked him his name — nothing. Just started shooting," said one witness, who would not give his name.Another witness, who also wished to speak anonymously, said deputies said little before they started shooting: "One officer goes up to the door, starts firing, never identified himself as the police ... still unloading on the car 30 rounds."
