Louis suburb were bracing for what nightfall might bring following more violence along West Florissant Avenue, the same thoroughfare that was the site of massive protests and rioting after Brown was fatally shot last year in a confrontation with a white Ferguson officer.

"Of course I'm worried," said Sandy Sansevere, a retired health care worker who volunteers at the retail store operated by the nonprofit group I Love Ferguson, which was formed after Brown's death to promote the community. "What scares me are the guns."

The father of the suspect who was shot called the police version of events "a bunch of lies." He said two girls who were with his son told him he was unarmed and had been drawn into a dispute involving two groups of young people.
