FERGUSON, Mo. Schools are closed for a second week. Tear gas canisters and other debris often litter the streets. Businesses are struggling.
The 10 days of protests and violence are taking their toll on this normally quiet city of 21,000 people 12 miles from St. Louis.
'This has to stop,' Missouri State Highway Patrol Capt. Johnson said Tuesday.
Johnson is charged with bringing peace to a city torn apart by violence since Michael Brown, 18, was fatally shot by a Ferguson police officer, setting off the angry protests that have made international headlines.
On Tuesday, more sad news. One person was reported dead after an officer-involved shooting in north St. Louis, just four miles from the protests sites in Ferguson, KSDK-TV in St. Louis reported.
In Ferguson, chools were closed and streets were quiet Tuesday, hours after peaceful demonstrations once again descended into chaos with police coming 'under heavy gunfire' and arresting 31 people. But everyone was bracing for whatever Tuesday night might bring.
Johnson said four police officers were injured by thrown rocks and bottles, at least two people were shot and two fires were set during another night of clashes between police and protesters that lasted into early Tuesday.
Johnson lauded local police, state troopers and National Guard personnel, saying they 'acted with restraint and calm.' He said police were shot at but did not fire any shots themselves.
'I don't want anyone to get hurt. I don't want an officer to get hurt, I don't want a citizen to get hurt. We have to find a way to stop it.'
The streets have been quiet during the day, but life has not returned to normal. The school year had been scheduled to begin more than a week ago, but Ferguson-Florissant district officials canceled classes last week due to the unrest. Then they canceled Monday. Now they say they will try for next Monday.
'This decision was made after much careful deliberation and consideration of input received from local law enforcement officials and District security staff,' the district said in a statement. 'We believe that closing schools for the rest of this week will allow needed time for peace and stability to be restored to our community and allow families to plan ahead for the additional days that children will be out of school.'
Ali Rafiq, whose parents have owned the Subway restaurant in the heart of the protest zone, told CNN the shop has lost about 60% of its daily revenue -- about $1,000 a day -- since the protests began. Rafiq blamed protesters and journalists for taking up parking spaces in the area, leaving few spots for customers.
'It's almost more of an issue to go up to people and ask them to move their car and get backlash,' said Rafiq. 'It's easier to let them park.'
Many protesters realize the violence has to stop. Monday night, a group of people trying to keep the peace locked arms and managed to position themselves between the more confrontational protesters and the police line. However, while many among the protesters clamored for calm, some in the crowd appeared determined to provoke an incident.
Johnson said some of those arrested were from as far away as New York and California part of what he called 'a dangerous dynamic of the night.'
'Our peaceful protesters are not the enemy,' Johnson said. 'Tonight we closed the roadway; we allowed those who come in peace to walk the roadway.'
And before the protests escalated, demonstrators crowded around well-known rapper Nelly, who is from St. Louis, and who was marching with protesters in Ferguson Monday night.
Nelly, who wore a white T-shirt with '#MikeBrown' stamped on it in black letters, cautioned the crowd to remain peaceful.
'It's a lot of people out for themselves that's out here right now,' Nelly said. 'They are overshadowing people.'
He added that people needed a solution that goes past traditional ways of protesting.
'The way we approach the problem is the same every single time,' Nelly said. 'We get angry. We march. We sing ... We don't strategize. All we do is react.'
A grand jury may begin hearing the case on Wednesday, according to the Associated Press. It was unclear how long it might take for a decision on whether Wilson should face criminal charges for Brown's death.
