Violence erupted in Milwaukee, Wisconsin, on Saturday after a black man was fatally shot by police. Police vehicles and four businesses were set on fire, according to WISN.

The man shot by police has been identified by family members as 23-year-old Sylville Smith. The officer who shot him is described as a 24-year-old black man with six years of experience, according to Fox 6. He has been placed on administrative leave.

One police officer is in the hospital after a brick was thrown through his squad car in the unrest that followed the shooting.

The riots also came after five people died of fatal shooting incidents which happened on Friday, August 12 and early Saturday, August 13.

Rioters can be heard chanting “black power” in a video at the scene of one of the riots.

Heavy spoke with a man, Tory Lowe, who was at the scene after the riots began. “This is after years of abuse by the police from 2011 until now. It has built up for so long, and now people are acting on it,” he said.

1. Police Say the Man Shot Was Carrying a Gun & Officers Were Wearing Body Cameras

The chaos began Saturday night in the hours after a Milwaukee police officer shot and killed an armed suspect, according to the Milwaukee Journal Sentinel.

The 23-year-old man killed in the shooting was fleeing from a traffic stop while armed with a stolen gun when he was shot by an officer about 3:30 p.m. in the city’s North Side. Milwaukee Police say.

The officer has been identified only as a 24-year-old male assigned to the department’s District 7. He has been an officer for three years and has worked for the department for six years. He was not injured and has been placed on administrative duty.

The shooting is being investigated by the Wisconsin Department of Justice’s Division of Criminal Investigation. Results of that probe will be turned over for a review by the Milwaukee County District Attorney’s Office.

The suspect’s sister posted to Facebook before the riots ensued:

Milwaukee Police Capt. Mark Stanmeyer said the man killed by police had a “lengthy arrest record,” but didn’t report any details of the past crimes. Investigators said the man’s gun came from a burglary in the neighboring town of Waukesha. The owner of the gun said 500 rounds of ammunition were also stolen.

“He was a nice good person, he was really respected. That’s why everyone came out. They’re angry,” YetNefataria Gordon told the Journal Sentinel.

At a news conference, Milwaukee Mayor Tom Barrett stated:

Police spotted a suspicious vehicle and they stopped the vehicle. As they stopped the vehicle, two individuals fled from the vehicle. One started heading west, another started heading east. A Milwaukee police officer with six years experience started chasing the individual who was running to the east. He ordered that individual to drop his gun. The individual did not drop his gun, held the gun, or I don’t know that for a fact, but had the gun with him. The officer shot several times. The individual was shot in the chest and once in the arm…that individual who is a 23-year-old man has died. The officer was wearing a body-camera. It is my understanding that the body camera was operating.

Barrett said he was at the scene after the shooting occurred, and that it was peaceful when he left earlier in evening.

“That officer had to make a split-second decision when the person confronted him with a handgun,” Milwaukee Police Assistant Chief Bill Jessup stated. “This is a risk they take every day on behalf of our community.”

A second suspect who fled on foot was apprehended and is in custody, Jessup said.

Rioters were reportedly firing shots, and first responders were unable to render aid to burning businesses, reported WTMJ.

Assistant Police Chief James Harpole said there were three people who were in the gas station when it was set ablaze, and all were able to safely escape.

As the chaos unfolded, officers got into their cars trying to leave when people in the crowd started smashing the windows of their squad cars.

Officers in riot gear moved cautiously into an intersection of the chaos later in the night, and told a crowd to disperse. Rioters reportedly threw rocks at police as they held up their shields, according to CBS.

Crowds chased reporters and a photographer from the Milwaukee Journal Sentinel, punching one reporter to the ground, the newspaper reported.

3. A Community Activist Said ‘This Has Been a Long Time Coming’

Heavy spoke with Tory Lowe, who lives in Milwaukee and was at the scene of the riots. Lowe said he is called a “community activist” among his peers. He stated:

I got there after the young man was killed. He had got shot in the back a couple times and he was running from the police. They called me and said I better get down there because people were pissed off…because the police just killed somebody.

Lowe said though the man killed had a weapon on him, people who called him to the scene said the suspect wasn’t “confronting” police with it. This contradicts a statement by Milwaukee Police Assistant Chief Bill Jessup, who said the “officer had to make a split-second decision when the person confronted him with a handgun.”

When asked if he condoned the violence, Lowe stated:

I don’t condone it. But I understand it. People are upset over the deaths of, let me see…we’ve got Derek Williams, James Perry, Corey Stingley, Brandon Johnson and Dontre Hamilton. Over 101 black men were illegally strip searched in Milwaukee. I’m talking pulling their pants down sticking their hands in their anal cavity with no gloves or anything. I’m talking about how bad it has been from 2011 until now.

He said citizens of Milwaukee are fighting for justice for these men, who were all killed by police or “failed by the system in Milwaukee.”

Lowe believes there were 200 people or more at the riots, and said word traveled fast to meet up after the police-involved shooting. He also said there is a huge problem with incarcerated black men in this particular area of the city. “53206 locks up more black men then any other zip code in the country,” he stated.

“Milwaukee is yet another example of why the Black Lives Matter Movement cannot be taken seriously,” Kenny Tobin tweeted.
