Several stores were looted and cars were damaged Sunday night amid protests for the shooting death of an 18-year-old unarmed black teen, Michael Brown, near St. Louis on Saturday. Brown was reportedly shot and killed by a police officer after a fight, which involved another person.

A few thousand people had gathered for a vigil for the high-school graduate, who was killed in Ferguson, a predominantly African-American suburb of St. Louis. An Associated Press, or AP, reporter saw people looting several stores near the shooting scene, and added that many of them carried loads of food products and other goods just after the vigil, in which people placed flowers and candles at the location where Brown was killed. Other eyewitnesses reportedly saw protesters damaging police cars, adding that officials did not intervene.

"We are currently experiencing a riot," a police dispatcher said, according to Reuters, adding that officers in riot gear had been sent to the site.

Earlier in the day, hundreds of local residents protested the shooting by shouting slogans like "No justice, no peace" and "We want answers."

The incident reportedly took place after an altercation between Brown, another man and the police officer. Authorities reportedly said that one of the men pushed the officer back into his patrol car and a shot was fired after a scuffle inside the car over the officer’s gun. After a few seconds, the officer shot Brown multiple times, while St. Louis County Police Chief Jon Belmar said they were not sure about the number of shots that killed Brown but said, "it was more than just a couple."

Ferguson Police Chief Tom Jackson said, according to AP, that authorities are still trying to understand what exactly happened inside the police car. He also reportedly said that the second person has not been charged or arrested, and authorities are not sure if he too was unarmed.

Brown's mother, Lesley McSpadden, reportedly said Sunday that the officer who killed her son should be fired and prosecuted. "I would like to see him go to jail with the death penalty," she said, according to AP.

"My son just turned 18 and graduated from high school, and he don't bother nobody,” McSpadden reportedly said, adding: "They told me how many times my son was shot. Eight.”

According to AP, the Rev. Al Sharpton said that the shooting death of the teenager was "very disturbing."
