FERGUSON, Mo. — Gunshots rang out after a car struck a protester during a demonstration in Ferguson, Miss., on the second anniversary of Michael Brown’s death, disrupting what had been a peaceful gathering but apparently striking no one.

Witnesses told The Associated Press that a car drove through a group of protesters who were blocking a street during the demonstration Tuesday night marking two years since the unarmed black 18-year-old’s fatal shooting by a white police officer. They said the car struck a young man so hard that he flew into the air.

Graphic video provided to AP by Heather De Mian, who was at the scene and frequently livestreams protests in the St. Louis area, appeared to corroborate the witnesses’ account, showing a man hit and thrown several feet as others nearby shriek.

The man seemed badly injured and was put into a private car to be taken to a hospital, Cowan said.

Shots can be heard on the video less than a minute after the collision. Some witnesses said protesters were firing at the vehicle, which a city spokesman later said was found to have bullet holes.

Spokesman Jeff Small told the St. Louis Post-Dispatch police don’t believe the driver intentionally struck the protester.

Brown was fatally shot by officer Darren Wilson after a confrontation on Aug. 9, 2014.

A state grand jury declined to press charges against Wilson.
