Protests and violence broke out across the United States following a St. Louis grand jury’s decision not to indict Ferguson, Missouri, police officer Darren Wilson for fatally shooting unarmed black teenager Michael Brown. The body of a 20-year-old black man was found shot to death and burned near the Brown family's apartment Tuesday morning while a march in Seattle turned violent, and protesters in Clayton, Missouri, shut down traffic.

The 20-year-old man was found in a car and the death is being treated as suspicious by St. Louis Police. There is no information regarding the identity of the man. Gunshots sounded throughout the night Monday and early Tuesday, and 14 people were reported injured during protests and subsequent violence, KMOX, St. Louis, reported. At least 80 people were arrested in the Ferguson area overnight, but police said they did not fire any shots. About a dozen buildings were reportedly burned in the St. Louis area, according to USA Today.

Seattle protesters reportedly threw rocks and fireworks at police who tried to clear them from an on ramp along Interstate 5. Police responded with flash grenades and pepper spray, but some protesters still managed to make it onto the highway. Five people were arrested, one on a weapons violation for carrying a handgun, KIRO-TV, Seattle, reported. There were also reports of vandalism in downtown Seattle. Recording artist Macklemore was among 200 or so protesters during an earlier, peaceful part of the march.

Protesters shut down traffic in front of the courthouse where the grand jury made its decision in Clayton, Missouri. A group of clergymen and their supporters laid down in the middle of the street to protest the decision while police reportedly helped stop traffic around the demonstration. Missouri National Guard troops were seen around Clayton, but Missouri Gov. Jay Nixon said they would only work in a support role.

Both Nixon and President Barack Obama appealed for peace following the grand jury decision. Volunteers took to the streets to help clean up burned out and looted buildings Tuesday.
