Stores looted, windows smashed after vigil for Missouri black man shot and killed by police

A day of anger over a fatal police shooting of an unarmed black man has turned to mayhem in suburban St. Louis as people looted businesses, vandalized vehicles and confronted police.

That followed a candlelight gathering Sunday for 18-year-old Michael Brown, who police said was shot multiple times after a scuffle involving the officer, Brown and another person in Ferguson.

Authorities set up blockades, trying to keep people from the most looted areas. Mayor James Knowles told KTVI-TV police were having a hard time catching looters because crimes were happening at several locations.

It wasn't immediately clear how many arrests were made or if there were injuries. A spokeswoman for the St. Louis County Executive said there was at least one instance of tear gas being used.
