As McCulloch was reading his statement, a crowd gathered around a car from which it was being broadcast on a stereo. When the decision was announced, Michael Brown's mother, Lesley McSpadden, who was sitting atop the car, burst into tears and began screaming before being whisked away by supporters.
The crowd erupted in anger, converging on the barricade where police in riot gear were standing. They pushed down the barricade and began pelting police with items, including a bullhorn. Police stood their ground.
The violence continued through the night Monday and authorities reported hearing hundreds of gunshots. Police have arrested at more than 80 protesters after crowds set fire to buildings and cars and looted businesses.
The Aug. 9 shooting inflamed tensions in the predominantly black St. Louis suburb that is patrolled by an overwhelmingly white police force. As Brown's body lay for hours in the center of a residential street, an angry crowd of onlookers gathered. Rioting and looting occurred the following night, and police responded with armored vehicles and tear gas.
