Segall-Gutierrez said witnesses reported that Evans had his hands on the car's steering wheel when he was shot and that he did not pose an immediate threat to the police officers.On Monday morning, family and friends accompanied Evans' mother Angela Naggie and her attorney to file a claim for damages at San Francisco City Hall.The group then marched with anti-police brutality activists to the San Francisco Police Department's administrative offices at the Hall of Justice, where they delivered the claim to the Police Department.Segall-Gutierrez said he plans to file a lawsuit for several million dollars against the city of San Francisco and the Police Department based on the claim that Evans' civil rights were violated the night he was shot and killed by police.Segall-Gutierrez said the shooting "was excessive, unreasonable and a violation of Evans' rights," and that it led to emotional distress for his mother as well as medical expenses, attorney fees, punitive damages, loss of income and general damages.He said police are "out of control" and officers need to follow department policies. He said he is demanding a jury trial to determine specific amounts to be awarded to Evans' mother.Naggie said officers in civilian clothing approached her son before fatally shooting him and said she still doesn't understand why they weren't in uniform.Naggie said her son's case is similar to one that just occurred earlier this month, resulting in the death 24-year-old San Francisco resident Alice Brown In that incident on March 17, plainclothes San Francisco police officers fatally shot Brown after she went on a driving rampage near the intersection of Van Ness Avenue and Pine Street.In the days after the shooting of her son, Naggie said that she believed the shooting was the result of racial bias on the part of officers.
