People smashed car windows and carried away armloads of looted goods from stores Sunday night after thousands of people packed a suburban St. Louis area at a vigil for an unarmed black man who was shot and killed by a police officer.

The candlelight gathering was for 18-year-old Michael Brown, who police said had been shot multiple times Saturday after a scuffle involving the officer, Brown and another person in Ferguson, a predominantly black suburb of the city.

Afterward, some people looted a convenience store. Several other stores along a main road near the shooting scene were broken into and looted, including a check-cashing store, a boutique and a small grocery store.

People were seen carrying bags of food and toilet paper. TV footage showed streams of people walking out of a liquor store carrying bottles of alcohol, and in some cases protesters were standing atop police cars or taunting officers who stood stoic, often in riot gear.

Other witnesses reported seeing people vandalize police cars and kick in windows. Television footage showed windows busted out of a TV station van.

"Right now, the small group of people are creating a huge mess," Ferguson's mayor, James Knowles, told St. Louis KTVI-TV. "Contributing to the unrest that is going on is not going to help. ... We're only hurting ourselves, only hurting our community, hurting our neighbors. There's nothing productive from this."

As the investigation of Brown's death progresses, "we understand people want to vent their frustrations. We understand they want to speak out," Knowles added. "We're going to obviously try to urge calm."

St. Louis County Executive Charlie Dooley said there were no reports of injuries but confirmed widespread property damage.
