A police officer shot and killed an armed man late Tuesday in Berkeley, Missouri, said St. Louis County police spokesman Brian Schellman.
Police say the man had pointed a gun at the officer, who fired out of fear for his own life.
The St. Louis Post-Dispatch reported that the dead man was Antonio Martin, age 18, citing his mother Toni Martin as its source.
Berkeley is a St. Louis suburb that borders on the city of Ferguson, where the controversial shooting of black teen Michael Brown by a white police officer triggered nationwide protests.
The officer with the City of Berkeley Police Department encountered two men during a routine check at a Mobil gas station, Schellman said. He got out of his squad car and approached them.
One of the men pointed a gun at the officer, who fired multiple shots at him, fatally wounding him. The second man fled.
Berkeley police asked St. Louis County police to handle the investigation of the shooting. The killed man’s handgun was recovered at the scene, Schellman said.
The gas station appeared to be outfitted with surveillance cameras, which were pointed at the parking lot.
Martin told CNN affiliate KMOV that her son had gone to see his girlfriend, who lived near the station and was with her at the time. She said the girlfriend notified her of her son’s shooting.
Martin said Antonio turned 18 in September. He had been expelled from school but was trying to get his life back together, she said, and she was encouraging him to join Job Corps.
Dozens of people stood across the street from the station, video from KMOV showed. There, they stood behind a police line. Some of them shouted at police and waved their fingers.
Among them were ministers and some who had protested in Ferguson after Brown’s shooting death, the Post-Dispatch reported.
About a dozen officers stood across from them, some speaking with them.
Video posted to YouTube showed a much larger group of officers, both black and white, gathered at the gas station, standing between protesters and the scene.
Two smoking objects flew toward the station. One of them emitted white smoke, while the other exploded.
