ST. LOUIS — A state senator and other black leaders on Thursday called for the Justice Department to investigate the fatal shooting of a black 18-year-old by a white St. Louis police officer, an incident that some protesters are likening to the death of Michael Brown in nearby Ferguson.St. Louis Police Chief Sam Dotson said the 18-year-old, identified by his mother and police as Vonderrit D. Myers, shot at the off-duty officer Wednesday night and the officer returned fire. The shooting led to an angry protest.Syreeta Myers told The Associated Press by phone Thursday that her son wasn’t armed, as police contend. She said he was holding a sandwich when he was killed, not a gun.“Police lie. They lied about Michael Brown, too,” she said.More than 20 black leaders gathered for a news conference outside police headquarters and questioned why the officer approached Vonderrit Myers in the first place.“This here was racial profiling turned deadly,” state Sen. Jamilah Nasheed said.The St. Louis Democrat said that in addition to requesting a Justice Department investigation, she will ask Missouri Gov. Jay Nixon to appoint a special panel to look into concerns about profiling and police use of deadly force. The Justice Department is already investigating the shooting of Brown on Aug. 9 in Ferguson. A state grand jury is still deciding if Darren Wilson, the white officer who shot the unarmed, black 18-year-old, will face charges.
